Both, thanks.
We adopted one DDs dachs when her life circumstances changed. He was about 12, and 2 years later he became diabetic and slowly, turned blind. But he was very happy and contented. And I did something that surprised even myself, never mind my OH, who was horrified. Bought him a buggy. He loved it- coming with us for walks, ears flapping in the wind. He went to Tuscany with us, and on a family ski holiday. He had a good 2 years (on daily insulin), thanks to the buggy- and even OH agreed it was the best thing to have done for him.
All our dogs have been strong and full members of the family, but always remained dogs.
