Dog Questions

I have a dog that loves dingo dog treats. I own 3 dogs and foster another 1-3 at the same time, so treats can become quite expensive. I’ve looked online and I’ve found some places that are cheaper than going to Wal-Mart, but after paying for the shipping adds up to being more. I’ve tried giving him generic dingos and he always knows the difference, when I come up the generic dingo is untouched. Does anyone know of a cheaper place to buy dingo dog treats? If you don’t, please don’t answer I don’t want a page of NO answers, I’m really looking for an answer to this. I only give the dogs treats if they will be alone for more than 4 hours, so they don’t get treats daily, but still it adds up. Thanks!
My dog does like them and I would never put bacon grease or any grease on something I was going to feed my dogs. The question is, does anyone know where to get them at a cheaper price?
Thanks for the answers, I think making my own is not an option, my husky is usually the smallest at about 40 lbs. I would have to cook for days to make treats for them all. I do sometimes foster a smaller dog, but generally do not as they scare my male german shepherd. For some reason a small dog gives him the heebies and at 103 lbs it’s tough getting him out from under something when a 5 lb dogs backs him in a corner, or the bathroom.
