I made the mistake of getting the dog vaccinated with Parvo at 2 months old due to the vet preaching about how he was so contagious. He is over 8 months old now and has not had a vaccination since then. I feed my dog mostly fresh pet chicken food and barkley's beef food (these are all frozen foods). And once a week feed him cooked chicken and/or beef with peas. I also feed him freeze dried chicken and salmon when treats when trying to train him. Once in a while the dog gets out of the yard and mingles wtih other dogs. I'm not sure what I'm feeding him is going to keep him from getting the diseases. I was at the vet picking up heart guard the other day and the tech made it sound like he was going to get parvo any day if I didn't vaccinate him. I also have a cat that does out at night and she is not vaccinated, but she was going out for years before she mostly became an inside cat so i'm assuming she has enough resistance to fight something off but I am concerned about the puppy. particularly since he's been not wanting to eat his food, but he will eat the chicken and potatoes and any bones etc so ti's not like hes not eating at all. It's just that he doesn't want that food. His energy is also good
