Behaviorist won’t hurt but from my experience excercise and leadership are the keys. My dogs had a rough winter before last, two fights and they were both serious fights. First fight in four years before that. This last winter was fine but we changed things up a little. No problems at all during the summer when they get lots of excercise.
@ginnyc I thought at the time it might be boredom with my B as he sometimes does lick himself during the winter when excercise is restricted. We had him on Benadryl and that stopped it, then switched diet. He hasn’t had any problems since. If the Benadryl works it should help if it is a behavior too.
I agree with Zande, also one of my dogs had problems years ago with allergy’s and had his glands expressed a few times with no improvement. If Benadryl helps I would consider it is possibly an allergy. Also contact the rescue where you found the dog as they may have more info or advice on the problem.
I find most problems like this are avoided if you tell visitors to ignore the dogs completely. I have had an assertive dog and a fearful aggressive dog. With both the answer was to ignore them and not try to pet them at all. Usually the dogs will become curious sooner or later and then they can pet them.
Consider an older dog, they are much less work at one year. Honestly, I used to think of older dogs as ‘used’ vs ‘new’ but the last Basenji we got was nine months old. No potty training, no ripping up everything, no teething, just an awesome dog right from the start. Plus if you adopt from BRAT you are helping a dog and get a lifetime of free support.
