We really don't know and would like some opinions from people who have maybe experienced this.
Our Westie is turning 17 this month, he has arthritis, his teeth aren't great, he has cataracts and his hearing isn't what it once was.
He still enjoys his food and slow walks outside, wanders around the garden and loves getting a scratch.
I don't think he will last another winter but would it be cruel to let him pass away in his own time?
I don't think he can be in constant pain as he does have good pain killers and isn't off his food and still has wet nose.
