My older terrier is 12, she has been getting increasingly aggressive for a few years but has reached a point where she is fighting with the other dogs daily and has bitten dd and snapped at me a few times. When we saw the vets about this a while ago they said they thought she had dementia. This was maybe 2 years ago.
She is often sick, I took her to the vets but they couldn't find anything.
She wees in the house and doesn't want to go for walks anymore.
But in between times she is chilled and happy. She eats well and is still seeing and pooing fine. She also makes really weird panting heavy breathing noises most of the time, again seen the vets about this but found nothing.
I don't think it's time yet but I think it might not be long now. But how do you know and when it is time what do you actually do, I was thinking of ringing the vets tomorrow to talk about her but I have no idea what to actually say.
