I've had a few dogs over the years and always will. However I have never had one make it to over 15 and we have a 3 1/2 pond yorkie that has. She's in pretty good shape but has lost most of here teeth so the poor girl is having trouble eating. Other than that she seems really, really good for her age and can still bust a move when she really has to. Seeing a 15 year old dog run is something that puts a smile on your face.
Anyway any advice on what to feed her? She will lick the sauce of some of the canned type foods and can eat some of the meat if we cut it small enough. We're also adding bone broth to try and get some nutrition in her. The thing is she still always seems hungry. To further complicate things we have a 3 year old Yorkie so can't just leave food down or you know what will happen.... For a while sous vide eggs worked but now she's bored with that. Is there anything you can think of that dogs find irresistible and is easy to eat with few teeth left?
One fun habit she has added to her arsenal is pawing the dog dish and getting water everywhere. We now put the water bowl on a puppy pad and that seems to at least keep the mess down. Our penthouse is 2 stories inside and she mostly stays downstairs now and can't manage the stairs on here own. Mind you some nights I am up and down the stairs about 20 times as her royal highness requests elevator service. Dogs are awesome and I don't mind caring for her in her old age as she has brought us so much happiness and love. But yeah it can be a challenge. When we got our last dog we figured Sheila would be gone in a year or so and were going to get a miniature dachshund so we'd have 2 dogs roughly the same age. That isn't happening now!
When we retire we plan on having at least old rescue dog to give it a happy end but now we can't really do that. So instead we donate a lot of money to the humane society here that is a non kill shelter. For some reason we also support the donkey sanctuary. That's OK it makes my wife happy and they do have a cute Christmas card.
