Dog's can eat almost anything that humans can. The easiest thing would be veggie burgers.

I think you should leave feeding the dog to your girlfriend if you don't know what it can and can't eat.

I thought this looked tasty

I would try calling a vet. I'm sure either the vet or the vet assistant would be willing to tell you what you can give the dog. My mom makes homemade doggie biscuits and our dogs go nuts for them. She uses flour. olive oil, and meat in a food processor then bakes them. However you could probably put veggies in it instead of the meat.

Because they'd rather them go to a loving home.

If they didn't care about their dogs, they would drop them off at the shelter , have them put to sleep, or give them to just anybody. Instead, they sell the dogs, making sure to screen the prospective owners carefully. Buying these retired show dogs is a great way to get a beautiful dog that has been very well brought up and taken care of. For people who don't have the time to go through the puppy stages, this is a wonderful chance to get a well-mannered, crate trained, housebroken dog of top quality, and at a discount price!

Most breeders live in homes just like you do and there are laws regarding how many pets you can keep. Not all show prospects do well in the ring. Not all breeding dogs produce as hoped for. In order to improve the breed, these dogs are taken out of the gene pool and placed into loving homes. Don't you see that as an act of caring?

Many of them just dont keep their adults once they are retired. Its not feasable for them to keep every single dog that comes into their lives. Many are still retired a fairly young age (around 5 years), and they feel the dog would be better as a pet, in a pet home.. with less competition from other dogs. Some breeders do manage to keep all or most of their dogs. I have seen some opt to alter and put a dog in a pet home simply because the dog doesnt cope well with the other dogs in the household. If the breeders did not care, then they'd continue to breed the dog a few more years, or they'd sell the dog to just anyone. Show breeders only let their dogs go to approved homes. Many I know let the dog go only for the cost of neuter/shipping.

They do care about them, but many cities have limits as to how many dogs one person can have. So when a dog is no longer showing or producing puppies, they are forced to either rehome the dog or cut back on breeding. Since they want to keep their bloodlines going, they can't cut back on breeding… so many older dogs have to go!

There is nothing wrong with them! I once adopted an older showdog who was very well socialized, friendly, housebroken, and obviously loved by her old owner who checked up on her regularly.

They are not all rehomed. Reputable breeders often keep them after they are retired. Commercial breeders will always rehome at retirement however, because the dog is no longer bringing in cash.

A dog that didn't perform well in the ring is nearly always re-homed because it is isn't being shown and can't be bred with that temperament, so it's the best choice for the dog. A dog that nervous often doesn't enjoy a busy, multi-dog household with loads of people coming in and out and an owner who travels to shows.

My mom has both retired dogs and one dog who was too shy to be shown at home with her now though. It depends on the breeder. She's ramping down as her physical ability to care for so many dogs declines.

A reputable breeder puts as much care and vetting into rehoming a dog as she did her pups.
