Via Cosh, a bizarre blog entry from a woman who is agonizing over having put down their English Setter after it put 40 stitches in the face of her husband. The post is too lengthy to fisk in its entirety, but I’ve chosen some key points; (note: link now dead)
Since late last summer Pony snapped twice at children who approached her unexpectedly when she was lying down, and once at me when I was wrestling with her on the floor. Until the first incident last August, we had been completely certain that she was flawlessly trustworthy with children and adults alike, and we’d taken her into the homes of friends who had children and encouraged kids in the park to pet and play with her if they showed an interest.
I wish I had a quarter for every time I witnessed completely clueless people encourage strangers to approach dogs that were telegraphing that they really would rather they didn’t. If you’re a typical pet owner with your first or second dog, there’s a 95% probability that you miss or misinterpret most of your dog’s communication signals.
We told people about the breed and that Pony was tolerant and good-natured (if a bit aloof in comparison to a Retriever or a Labrador), and they should have no qualms about approaching and touching her whenever they liked. When she barked and scratched at our friend’s son last summer it was an enormous shock and completely rattled our foundation of trust in her.
The dog was an English Setter. English Setter colour is “extreme white”, with coloured ticking in a genetic pattern that resembles that of the Dalmatian. This is important – the all-white colouring is thought to be the result of a gene that creates a deficiency of neural crest cells, which differentiate to function in several ways – some important, some not. One of the important functions is the development of the brain and nervous system. The least important function is to produce melanocytes, the cells that create pigment in the skin and coat. If the neural crest cell deficiency is extreme, the dog will be unable to create significant areas of pigment, resulting in white hair coat, with pink skin underlying it.
Why is this relevant? Because if there aren’t enough neural crest cells to produce pigment creating melanocytes, there may not be enough for the development of nerves required for normal hearing. This problem is so well known that many breeders test hearing (BAER testing) as part of the veterinary screening protocol before sale. For this reason, it is suspected that (like Dalmatians, Jack Russel Terriers, white Bull Terriers, etc.) that a percentage of English Setters are deaf, or partially deaf. (Which may explain why they seem so tolerant of their own incessant barking.)
So, go back to the top and reread the comments about the dog’s snapping when being approached unexpectedly – the context changes a little. Later in the post, she describes the dog’s “hairy eyeball and some serious stubbornness”. While it’s quite possible that this dog had normal hearing, it is not unexpected behavior from a deaf dog.
Then, she made another innocent error – she consulted “dog experts”.
