I'm guessing that is why his delightful owners dropped him off to the kill pound at the grand old age of 14.
I didn't know at the time that he had dogzheimers, it was only when we got him home, and the howling at the walls, and the walking into things started that we begun to realize.
Prince has days where he is great, he is with us, he knows his name, and responds to everything. Then there are other days where he is simply...... somewhere else.
Although Prince is a challenge usually at 3am when he is pacing, and howling, and you have to explain who he is. Some people struggle to understand this, and ask why we don't simply put him down.
This always amazes me, and I do ponder if they would simply put their granny down if she got old, and needed care. he is one of us, and he isn't going anywhere!
