April,
It is a myth that dry food cleans teeth. That would be like granola cleaning ours; it doesn’t. I believe a wet food is better for dogs with stones but I am not positive.
Regarding the surgery, you can apply for Care Credit through your vet. You can also sell anything that would bring in money. Other than that, you could start a Go Fund Me page but don’t be surprised if you don’t get many donations from strangers. Beside it being Christmas & a hard economy, some feel that pet owners are supposed to have something already in place for emergencies, myself included.
I wish you luck.
