I'm not trying to put Westy six feet under. Westy, the nicest and grumpiest old man, has been trying to do that to himself....very much prematurely. He has been less grumpy since he got Red Rover, though.
Yes, the pet door is a great idea. Do your suppose he might want a poodle dog or another breed?
(Westy, I love you)
.....Westy.....
They are wonderful companions. Both my FIL and BIL's family had several of them. Just great animals.
