We rehomed a 15yr old spaniel cross about 10 yrs ago. my sister emigrated and as he was on heart medication he couldn't travel that far he was also deaf. He was lovely . Often when I came home at lunch time to let him out for a wee unless there was a draught from the front door he wouldn't wake up so I had to nudge his basket. luckily we had a large garden as he had no recall so was always on a long lead when we went out for a walk. The vet said let him go at his own pace which was slow unless he smelt a bitch on heat then he would be off like a rocket. Which came as a bit as a shock. He enjoyed live till he was 17. A grand old boy.
