As the 75-pound male shepherd mix squatted to urinate on the floor just 10 minutes into our consult, I hinted to the owners who were seated between the urinating dog and me, “The paper towels are hanging on the post right next to Ferdinand.” Since the owners were way closer to the paper towels than I was and theirs was the dog pottying inside the behavior consult room, I assumed they would clean up the mess. Not so! So, I decided I’d better clean it up myself.
Although the dog was presenting for fear (aggression) to unfamiliar people, I’d already greeted the dog, he was comfortable taking treats, AND the owners had marked in the preconsult records that he had never bitten anyone before. As I got up to walk past the owners toward the papers towels and the accident, I noted Ferdinand’s demeanor. He was relaxed and still interested in exploring the room. Fearful dogs suddenly can become scared and reactive when the person they’re nervous around changes posture, moves suddenly, or approaches them, especially head-on. Ferdinand showed no such signs of anxiety or reactivity.
Furthermore, although the owners had brought him in on a muzzle, they had asked to take it off now that he was in the room and looked comfortable. They said that he only was fearful of some people. They reiterated that, as the preconsult form stated, he had never bitten before. We decided to let him explore the room while dragging his leash, so that I could evaluate his uninhibited behavior in the new environment.
As I dropped the paper towels onto the floor and then stepped on them to sop up the dog’s mess, I continued to question the owners about Ferdinand’s history. “How many aggressive or reactive incidences does he have per week? How do you handle the situations? What’s his response to your handling technique?”
When all the urine was soaked up, it was time to collect the paper towels and dispose of them. Normally when I’m in the room with a dog who’s fearful and reactive, the dog would be on leash. In addition, I might avoid facing him head-on even to pick up something off the ground. But, based on the owners’ experience, Ferdinand was not likely to react at this point. Plus he was over 10 feet away. I casually bent down to pick up the paper towels. Then I hear, “Bark! Bark! Bark!!” and feel teeth on both sides of my head.
The owners quickly had him by the leash and pulled him away from me so it wasn’t a serious or even scary event for me. Plus, I was pretty sure that there were no marks on my head. However, that didn’t stop me from being peeved.
I emphasized to the owners, “You know that counts as a bite.” I thought to myself, “When you told me he had no history of biting, you forgot to include that you didn’t count the times that your dog rushed a person and grabbed a body part in their mouth as a bite!”
Based on the response of this dog, I could tell this wasn’t Ferdinand’s first time acting like this. He’d clearly had some practice sessions barking, lunging and putting his teeth on skin. A first timer facing the same level of threat or scariness—me leaning over from far away while not looking at him—might run up and bark at me but would just snap or nip with his front teeth, rather than actually grabbing my head like he was trying to taste a cantaloupe with his teeth. If he’d had tons of practice or intent to harm he’d have actually bitten down or clamped on in the same way he does when he mangles his tug toys. Or if he was scared out of his mind by my movement he would have kept biting, even if it was only a soft bite owing to lack of enough confidence to bite hard. But it was still a bite; the owners should have known that it could happen and should have had Ferdinand on leash or still wearing his muzzle.
How could the owners have been so naïve about their dog’s behavior? Usually when people think about bites and aggression, they think about mauling or think the dog has to intend to be mean. However, Ferdinand’s biting behavior, although mild, was cause for concern.

“Some Bites Can Kill”Surprisingly, even with serious bites, sometimes it doesn’t click for owners. Says, Dr. Emily Levine, a veterinary behaviorist at Animal Emergency and Referral Associates in New Jersey, “I recently saw a 2 or 3 year old intact male English Bulldog in a behavior consult. The dog was staying at the owner’s mother’s house. She thought the dog was crated. She went to open the door for her friend who was there holding her baby. The dog saw the visitor, ran straight towards her and bit her legs. The dog bit through muscle down to bone. They owner had a difficult time getting the dog off of the visitor. The visitor needed 90 stitches and will likely need plastic surgery,” continued Dr. Levine.
You would think that a person would clearly see how dangerous this situation is; however, according to Levine, this family had no real experience with aggressive dogs. Says Levine, “The owners had been instructed by Animal Control to quarantine the dog, which they did, but because they never received a visit from the Animal Control Officer at the end of the 10 day quarantine, the owner thought that perhaps this degree of bite was not out of the norm.” In the owner’s view, since the Animal Control Officer didn’t seem concerned enough to make a return visit, the bite must not pose any future threat.
Luckily the owner did seek a behavior consult. “Once they were educated about the fact that this was a very severe bite and after I went through the risk and benefits of a behavior plan, they decided that the risks outweighed the benefits for them.
They understood that even if they were extremely vigilant and did a great job with the behavior modification plan, fantastic results are not a guarantee.
“They realized that this could happen again and that this dog could literally kill someone,” says Levine. “If the person he had attacked was a short person or a child, it would have been the neck he grabbed hold of.” The owners decided to euthanize their dog.
Although aggressive behavior can be modified in a huge range of cases, behavior modification is not like fixing a clock or a television set where you make a few changes and then it’s good for another five years. Dogs are living animals and behavior is something you can never guarantee 100%. Based on her findings with this particular dog and family, Dr. Levine says, “I believe the owners did the right thing. I fully supported this choice.”

Dr. Dodds believes thyroiditis is often misdiagnosed or missed altogether. She wants to increase awareness of the early signs of the disease in both the veterinary community and among animal guardians, something she hopes will reduce unnecessary euthanasias.

Whether we like it or not, we need to recognize that the wide range of behaviors labeled as aggression are communications from the dog to us. Dogs do not snap, snarl, growl, or bite without reason, and those reasons can range from feeling afraid to being confidently challenging.
