This is an email question from a DogTime Blog reader. It is about a Labrador named Lucy who suddenly became aggressive to her owner during training classes.
The owner stated that Lucy does well with heel, sit & down stay, leave-it unless there is a distraction such as a ball. "Lucy... ignores the other toy distractions and only fixates on the balls. Naturally, she struggles with maintaining her focus on me and my commands during this exercise, but we do have moments of success. She will leave it, but still maintains a fixated focus and trembles with excitement."
But Trouble is brewing...
In the email Lucy's owner reported: "This week in training Lucy was so agitated during this exercise that she snapped at me 3 times when I corrected her and snapped at other dogs in class. It is like the training, though having some positive affect, is actually bringing out the worse in my dog."
Lucy's owner is alarmed because, "In her two years, Lucy has never, ever snapped at anyone or any other dog during play or on walks. I have expressed this concern with the trainer, and her feeling is that this behavior was just in there waiting to come out. I am just not sure about that explanation and thought I would share my story with someone else."
I asked Marianne to share more with me about how she is teaching Lucy to LEAVE-IT.
Marianne reported: "We are using a standard slip chain choke collar. I snap and release the collar to correct. On the snap, I say "uh uh" (hard to spell that!), then give the command. For example, to have her ignore a ball or toy, I tell her to "leave it. If she goes for it, I snap and release the collar, say "uh, uh" and repeat "leave it".
"When she reacts correctly, I give verbal praise in a softer, higher tone of voice, such as "good leave it" or "good heel". Frequently, during our training, I stroke her and give her positive verbal feedback...no treats until the end of class."
There are several problems with the way that Marianne is being instructed to teach her dog. I will summarize my concerns and the errors in the training below.
However, I want to be VERY CLEAR about TWO THINGS.
1. Marianne did nothing wrong. She enrolled her dog training class with someone whom she was told was an expert. Dog training is still an unregulated field. Many of us, myself included are looking forward to the day when all trainers will need to be certified and/or licensed. As it is now, anyone can call themselves a trainer. There are a few Certifications Programs in the U.S.
2. The following is NOT MY OPINION. Training is a SCIENCE. This means that there are rules. While I have my own personal standards for "humane training" I am not at this moment referring to HOW you get the job done. I am instead referring to HOW ANIMALS LEARN. A good trainer should have a solid basis in understanding Operant & Classical Conditioning regardless of whether they give out cookies, collar corrections, or both. Without these fundamentals skills they are not prepared to train a dog. Would you go to a doctor that you overheard saying: "Veins, Arteries, whatever; they both do blood stuff!" I didn't think so.
So What Is Going On With Lucy? Is she turning aggressive?
For starters, Lucy's aggression was a trained response. It was unintentional, but it was taught. Specifically Lucy was taught to HATE seeing Tennis balls in class. Lucy was being asked to perform a task that she could not do, and because she was not given any guidance on the correct response (look away from the ball) her training looked like this.
Tennis Balls Appear In Class -------> Lucy is subjected to a barrage of jerks, snaps and chokes.
Punishment is a crude tool and has the potential for causing aggression. In this case, Lucy began to associate the tennis ball distraction with pain. All animals like to avoid pain and at some point will either choose to fight back or flee. As Lucy was on-leash fleeing was not an option.
An even more astonishing is that Lucy was never shown WHAT TO DO. When I want a dog to perform a Leave-it, I like to focus on what that looks like when the dogs gets it right (look away, sit, look at handler). There are countless ways to get something wrong, and generally only a few correct responses. Focussing on the correct response is not just nicer for the dog, but gives faster and eliminates the side-effects (ruined relationship, fearful dog, aggression) of aversive punishments.
What I would have done to train Lucy.
Bounce a Distraction-ball until Lucy notices the ball.
Have Lucy's owner give the Command (say, "Leave-it") the moment Lucy notices the distraction-ball.
Stop bouncing the Distraction-ball (kindergarten level) & Give Lucy a moment to respond on her own, by looking away.
Help Lucy get it right a few times (look away from the ball) by having the handler produce a Hint (squeaky tennis ball).
Praise Lucy at the exact moment that she looks away from the original distraction-ball (even if she is just listening to the hint).
Reward Lucy with something she really, really wanted A BALL!
Repeat this until Lucy looks away from the original Distraction-ball on her own BEFORE the Hint & reward Lucy with both balls and end the lesson. Review later and continue to raise the expectations until the hint is no longer needed and the reward is expected to be random.
Your dog is NOT being naughty...
On purpose,
To get back at you,
Or, because they are trying to dominate you!
Your dog's behavior is not malicious.
Behavior is a result of past CONSEQUENCES & current MOTIVATIONS.
Chances are they...
a) Really DON'T know better.
-
They are acting on instinct (dogs bark, whine and chase things).
-
They are doing what feels best to them (peeing and pooping feels better than holding it).
-
They are repeating something that has worked before (checking the counter for more toast).

They are repeating something that has worked before (checking the counter for more toast).
b) Just don't care.
-
There is no yucky consequences (peeing on rug = relief).
-
The consequence is late or seems unconnected (yell at dog for chewing couch sometime while you were gone).
-
The consequence is actually rewarding the behavior (pushing a dog down for jumping up = touch/attention).
-
Something else is more compelling/appealing at the moment (pulling towards the next great smell is worth the choking sensation).

Things to think about...
Have you ever done something even though you "knew better?"
Have you ever performed poorly at something you "know how to do?"
Have you ever made a bad meal or burnt dinner?
Did you do it to "get back" at someone or as revenge, or was it just the way things went?
Did everyone notice how "in charge" you were of their food enjoyment and "feel subordinate" to you?
Have you ever missed a payment or fogotten something important?
Was it to "make a statement" about something, or prove your power?
Did you do it "on purpose" even though you "knew better" and had done it right before?
Do you know better than to call in sick when your friend is visiting?
What is your motivation?
What is the consequence?
Are you a "good" driver?
Have you ever sped?
Why, it is "wrong" isn't it?
Have you ever been "sneaky" about when/where you speed? Why?
Dear Kelley,
I pray you can help me. Last year I rescued a dog, and myself + my family showered her with love. She had had a very distressing past history, this reinforced to us when she bit my Mother In Law on her third day with us. They were very serious bites and our vet said we had no option but to put her down as she had a high risk of re-offending.

We, as a family, found this incredibly difficult but had no choice. She was a beautiful 2 yr old collie and it was so heartbreaking. We recently re-homed a 6-month old German Shepherd who is a real sweetheart.
However we have just realized that our 12 yr old daughter is still traumatized by the incident with my Mother In Law (which she witnessed).
Krya jumped up to lick her and she had a panic attack. My question to you is "Is it better to put a muzzle on a dog we all love or let her move to a home where she does not have that restraint? She would get plenty of stimulation with us, walks beside a canal for 2 hrs a day, hill walking/climbing regularly with loads of love + attention. Please let me know which outcome would be better for Kyra as it is her welfare that is at the forefront of our dilemma.
Kind regards, Linda
Facts & Summary:
- "Kyra" is your new, 6-mo. old German Shepherd Dog.
- Your daughter, age 12, was recently witness to a severe bite inflicted by a different dog to a family member.
- The dog who bit was a 3-day, newly adopted, 2-yr old Collie.
- The Collie was euthanized for aggression as recommended by your vet.
- Although the new dog is friendly, she is rambunctious and untrained.
- Your daughter is having panic attacks whenever the dog jumps up on her, licks her or does both.
QUESTION:
Should you use a a muzzle on the new dog, so that your daughter will not have to worry about being bitten. Or, is this unfair to the dog?
First, let me say that if your daughters fear is severe, or getting worse, you may want to seek help from a mental health professional.
It is entirely normal to be afraid of large animals with big teeth! But it sounds as if you are describing a new change in your daughter that is drastically different because of a specific event.
Given the bite your daughter witnessed and the events that followed, I am not surprised that your daughter is having a difficult time bonding with your new dog.
If you can't manage the access the two have to each other with gates, crates, and tie-downs while still providing excellent opportunities for mental and physical exercise for the dog, then you may want to re-home the GSD.
If you are able to find professional help for your daughter and the prognosis is good, then it might be possible to temporarily manage the situation and work through the issue.
Having worked as a humane educator I do have some experience working with social workers and psychologists in controlled settings with dogs and children who were fearful of, or had had a traumatic experience with an aggressive dog. It takes time to recover from a bad experience and steady, slow progress is best.
From a dog-behavior perspective, "wiggly" & "overly-friendly" are encouraging terms. They mean that the dog is not afraid (potential fear-aggression), just untrained. Untrained is fixable with patience and a little work. The dog's temperament aside, the human needs to be comfortable too and wiggly/friendly can be just too much for a fearful person.
When working with people who are afraid of dogs, I have never started with a puppy! They are TOO-WIGGLY! A friendly, well-trained adult dog who listens well to commands is ideal. So, don't peg your daughters recovery on your puppy. Consider training the puppy and getting your daughter (at her comfort level) interacting with older, well-behaved, friendly dogs.
Regarding your specific question, I would NOT recommend muzzling the dog.
I only use muzzles when the is a clear indication that a bite is likely and/or a previously known history of the dog having bitten or fought.
If this is a concern (that the GSD may have some tendency to bite or nip) than it may be best to re-home the dog and focus on your daughter's feelings and concerns regarding dogs.
If the dog is not currently biting or showing signs of being fearful or aggressive, then it is your daughter whom you need to turn your energy.
Muzzling the dog will not fix your daughter's fear, but could give her a false sense of security.
Furthermore, your 6-month old pup will miss out on the opportunity she needs to learn what (toys) she is allowed to put her mouth on and when (never), she may place (even gently) her mouth on people.
If the dog is NOT biting or puppy-nipping then by all means, please use other management devices such as crates, pens or tie-downs to prevent the dog from jumping all over your daughter.
This is just good-sense for anyone with a rude, jumpy pup.
Preventing the dog from practicing the bad behavior is critical to training.
Finally, please enroll in a Reward-Based (no choke/prong collars) Training Class.
Don't forget to include your daughter in training the dog. The class may be overwhelming, lots of young, un-trained dogs, but your daughter could be included in the homework exercises.
In the beginning this may mean that someone else holds the leash and controls the dog from a distance, or that your daughter gives the commands or food-rewards.
Hi Kelley,
I am interested in your ideas and teaches learning about your knowledge on training tips for dogs. I have german shepherd solid black and he is now 5 mos. old. I have a very big problem on him; he eats his feces whenever he urg's his butt he turned around, smell it and grab!! ew!. What i always did is i keep on eye with him whenever he had a heavy play after sometime when turned around by itself then it will be. When he started to smell it i will immediately shouted to him "NO" then he leave and play again. Please help, what should i do? because when i am not around he still eat his feces.

Dear Jo-ann,
I know that Poop Eating (Coprophagia) is a disgusting behavior, but it is unlikely to MAKE your dog sick, so at least you can let that worry go. It will be easier for you and your dog if you remain calm during training -even if he relapses. The causes of Coprophagia are not fully understood. However, veterinarians, behaviorists and trainers generally agree that it is a behavioral problem. On the other side of the coin, there are a handful illnesses that can cause coprophagia (poop eating), but they generally present with more symptoms, including diarrhea. To be on the safe-side, take your dog to the vet, especially if your dog has diarrhea and or has not been to the vet for vaccinations.

Once you know your dog is healthy, the following training plan should help.
1. Know that STRESS is the enemy. Your dog is very young and he may still be nervous, or stressed out about going to the bathroom. Stress is the cause of many undesirable canine behaviors. Believe it or not, there is a lot that can stress a 5-month old a puppy. They are learning to hold their bladder and bowels, as opposed to just going whenever they feel like it. They are also still in the process of learning when and where they may go to the bathroom. I know your shepherd is getting big, but he is still a baby. Potty-training a pup can be frustrating, but avoid punishing mistakes. Instead tighten up on management and forgive mistakes.
2. Do NOT let GOOD BEHAVIOR go unnoticed. Reward your dog every time he goes to the bathroom in the appropriate place. As soon as your dog has finished PEEING or POOPING, use your best happy voice to praise him. Then feed him a tasty treat. Toss a second treat away from the poop to distract your dog while you remove the poop with a scoop or bag. If you have already been doing this, continue and make sure that you do it for BOTH pees and poops. I would skip shouting "No!" this could cause more stress. Just wiggle the dog treat and praise your dog, so that his attention is on you and he leaves the poop alone.
3. CLEAN UP! Always join your dog on potty walks so that you can reward your dog and scoop the poop immediately.
4. INCREASE EXERCISE & MENTAL STIMULATION. Make sure that your dog is getting plenty of vigorous exercise each day. A 5-month old Shepherd could probably use at least two 1-hour play sessions each day. This means running, fetching, hiking, playing with dogs. More is always better. And, when you leave your dog alone, make sure that your dog has plenty of things to CHEW. Bones and Kongs are best.
5. Try adding a supplement to your dog's food so that the poop will be unappealing to your dog. There are several products, listed below, but I have also heard various recommendations on adding enzymes to your dog's food. The theory is that if poop-eating is caused by under-digestion (eat the poop to give a second go at getting all the nutrients), then the enzymes help the food become more digestible.
At this point, regardless of the CAUSE, there is also a BAD HABIT. I recommend trying the supplements IN ADDITION to doing the behavior modification work. If you are only going to do one, try the behavior stuff first (its free), then buy a supplement if there is no change in behavior after 3-weeks.
- Forbid (TM)(R)
- Deter (TM)(R)
- Papaya, Fig or Pinneaple (These food contain enzymes that break down amino acids).
- Meat Tenderizer (from a grocery store) contains enzymes that break down protein.

- You are NOT chasing your dog. I agree, he would think that is fun.
- You are approaching him casually and TRYING TO TRADE TREATS for the ITEM.
- You have supplied your dog with HIS OWN TOYS.

The motivational issue.
The management issue.
A possible health concern.
My major suggestions would be:
Create a BACK-UP PLAN.
- Have some really amazing treats (steak comes to mind).
- Set your dog up. Deliberately leave an old-expendable sock in a steal-location, or drop it "by accident."
- Say, "TRADE YOU!"
- Then go to the fridge (yep walk away from your dog) and get the goodies.
- Without saying anything more, toss (stay as far away from your dog as you can) the yummy-steak treats AND WALK AWAY.
- If your dog appears WITHOUT the ITEM... Praise your dog like mad and give MORE TREATS.
- Tether, crate, or confine your dog and then go recover the item.
Do this until the dog spits out the item as soon as you toss the treats.
DO NOT touch the item or try to take it if your dog is still holding it, or standing over it.
Continue to work DROP with the tug toy, then try DROP with a sock that you are holding.
