Please be gentle, I'm really upset. I have a 6 year old Patterdale bitch who is normally reactive and vocal to other dogs and stays on a short lead. We were walking yesterday on a narrow path and she bit another dogs lip. She was still tail wagging, no hackles,no growling, wasn't even barking! We rehomed her from a friends Dad as he was made homeless, and weren't told about her issues, 8 months ago and she has got a lot better since then other than yesterday.
What do I do now? The other owner was really lovely and obviously appreciated that I was really apologetic and ended up standing in a bog toget her away. We've seen a behaviourist and that seemed to help her in terms of her excessive barking at home (still barks a lot but not 24/7) and other issues around resource guarding, but I am so out of my depth on this one.
Apologies for typos, my tablet has a mind of it's own and my 3 year old is 'helping'. Any advice very much appreciated.
