Dog growling/snarling at 1 year old...
I don't know if I'm looking for advice or commiseration, but our beloved 5 year old lab/dalmatian mix is growling and snarling his teeth at our 1 year old. We are due with a daughter on April 1st, so we see the kid situation getting worse, not better.
We were hoping to reduce this behavior using training and exercise, but to no avail. The lab has had a year of intense training, and does most commands well, but is still extremely anxious and occasionally aggressive towards other dogs and children. We bought a treadmill to exercise him, which I do most days twice a day, and he hates it. I bought a device to take him on bike rides with me, which he seems to enjoy. But even after long, intense exercise, the lab will be exhausted, but if my son crawls by, the lab will growl and snarl.
All of this came to a head recently when we were cooking some hamburger in the kitchen. The lab was sitting watching us, and our other dog, a 2 year old golden, must have startled him--the lab whipped around and bit her on the nose, drawing a bit of blood in one spot. Had that been our son... I can't even imagine.
Any thoughts or advice? The vet said we need to get him out of the house. Our trainer said this doesn't seem like the kind of aggression that would lead to biting, particularly for a dog that has never bitten. We're fairly convinced this just isn't worth the risk. There is a local no-kill shelter who may be able to take him, or we could try to craigslist him to a good family. All of the options here are heartbreaking. Thanks for reading.
