My cousin who is in her eighties wouldn't be without a dog, and she gets them from a dog rescue centre. Unfortunately, they all seem to be rather aged, and she loses them on a regular basis, but they have a wonderful home for the latter part of their lives [I'm not sure which charity she goes to]. I've read about the Cinnamon Trust and they sound very good. I would imagine it's easier to rehome a dog than a cat. When I lost my last dog, I said I wasn't going to have another, but my partner persuaded me to have another and I'm so glad he did. Also, reputable dog breeders often need to rehome bitches that are too old for breeding; I have whippets [can't recommend them enough, because all they want is to sit on the sofa with you and watch television, and they are so sweet and gentle] and the breeder I used to buy from offered me an older bitch; I didn't accept because I like to have a dog from a puppy so I know it's temperament]. I used to have cats as well, but I find whippets are like a cat substitute..however, don't even attempt to keep them off the furniture; they feel it's where they belong, and they're such clean dogs it doesn't really matter.
