my german pointer aged 9 yrs was in perfect health all her life from puppy on. A few months ago she started to favor her right side and started bumping into things. With in a week she had gotten progressively worse to the point she couldnt stand up and shortly after died. In your opinion did she have a brain tumor or suffered a stroke. (She was a hyper dog and suffered separation anxiety.
This is possible. Sorry for your loss. Vetcare
