We’ve got a six-year-old female, Nollie & about eight months ago we added an 8 week old male puppy - Pumbaa. Both dogs have been fixed. So the little guy is now 10 months old, over the last few weeks they have gotten into five pretty bad fights, they’ve pretty much escalated and gotten worse every time with the last one resulting in stitches for Nollie. It’s really weird because they had a really great bond and have been best friends for the last six months. Around the same time with the fights started it was discovered that she had a cyst or actually turned out to be a non-cancerous tumor on her leg down near her paw. We ended up having that removed about 10 days ago so she is recovering. We’ve been keeping the dogs separate for eating and sleeping and actually most of the day. We’ve gotten them together here & there very carefully and there had been no issues until today. The little guy licked her on the face, kind of gave her a kiss and then laid down next to her, as soon as he laid down she tried to attack him again. We were able to pull them apart without any damage. How do we get back to where we were? The vet is telling us we’re doing something wrong and is suggesting a trainer and giving Nollie fairly heavy doses of sedatives, which she says are going to be long term. The female has never really liked other dogs but it sure seems like something is especially off with her right now, you can see it in her face, She really doesn’t want me to pet her shit and she wants to be on her own, regularly leaves the rest of the family and lays down in another room by herself which she never really did before. I don’t want to get rid of either of these dogs, I don’t know what to do but I know I don’t have money for tons more medication and dog training. Any ideas?
