about the difficult thing about owning a dog, I think that could apply to owning a cat, too!
Dying that is.
We had both for many ,many years our dog travelled with us as we moved interstate over 2000 miles by car and our cat came down by plane once we had settled in .
I cried when both eventually passed and especially with our toy poodle "Lillie" that became my dog we had them both for about 16 years,
