The kids are out of the house, the grandchildren visit every now and then, but that doesn’t mean you can’t have the pitter patter of little feet. Pets can be great companions when you retire. But maybe not a puppy. Groups like Pets for Seniors, can link you up with an older cat or a dog that is already house trained and isn’t going to drag you down the block on every walk. Many shelters have older dogs that need homes and in some cases the fees are nominal.
