We have 2 dogs, one is 5 years old, slightly bigger then the other. The smaller one is just 3 years old.
About 4-5 months ago all of a sudden they started fighting, or better said, our bigger dog started attacking the smaller one. A couple of weeks and fights passed. We corrected it every time and used tools and tips we found in the past.
For example, they stay apart from each other when we are not home.
It got better, for a couple of months, and now they started again, twice this last week. We are going for medical check up this afternoon but we are kind of lost.
Any help? All tips welcome, we love them both to death and can’t stand to lose one..
Extra information: Both adopted from shelters relocating animals within Europe. Both female. No other altercations in the past years.
