We got a rescue dog when he was 5, he is now 9. At the time we were a childless couple, we now have a 2 year old. Our dog is a border terrier/jack russell. We don't know anything about his background but he was well trained yet quite needy but a beautifully friendly boy. We have been mainly stay at home with him (we got him 7 weeks before lockdown, not knowing what was to come) and there have been issues which with support from a behaviourist we realised were (not easily recognisable) anxiety issues. Working with her and the vet he has been on medication for the past year which has taken the edge off but not been 'a cure'. Wanting to help him further we decided to try a new medication on the vet's advice. We had to wean him off all meds before starting this new one 2 days ago. Having always been so tolerant of our toddler, tonight he bit him, on the face. It's superficial and he is ok but where does that leave us? We will obviously phone the vet in the morning but I'm so torn between feeling it's my fault for leaving our dog so vulnerable on basically no meds but not knowing if I can ever trust him again. They were not left alone and it was a split second reaction we couldn't control to our toddler trying to grab his toy back. Is it an absolute he has to go or is there an option to try to work it out going back on original meds (which he had no aggression at all with, just other issues)
I know those without without a family dog will have an obvious opinion but has anyone experienced anything similar? I will go with the vets advice but if it's to go back on the original meds and continue, does anyone have experience with this? It was so out of character for him and he's not an aggressive dog as such (I know all animals are unpredictable) Obviously my child comes first and they would be kept completely apart until we come to a conclusion but it breaks my heart to think of losing our otherwise affectionate, fun boy.
I know the knee jerk from everyone having not experienced anything like this would be to get rid so please only comment if you have experience with dogs, I do desperately want the best for everyone.
