A few weeks ago I was grooming Lily on her leg, and she suddenly growled and snapped at my hand, not like she was actually going to bite but as a warning. Her leg had been sore lately, so I immediately assumed it was out of pain. I took her to the vet a few days later, and they put her on pain meds and suggested x-rays to find out what’s going on. We’re still getting to the bottom of it, but I realized that Lily had actually been in quite a bit of pain and that was her way of showing it. Since your boyfriend wasn’t actually touching the dog, it is unlikely that he caused her any pain but she could be in pain anyway from being pregnant. I wouldn’t regard it as a behavioral issue just yet. If it keeps happening, I would recommend taking her to the vet, and if she gets a clean bill of health then you could look into getting help from a trainer.
