Hello. I have two puppies, Annie and Logan, who survived Parvo. They will be a year old in September but Annie only weighs maybe 20 pounds and Logan weighs 40. They are full blooded but I guess the parvo stunted their growth, Annie's more than Logan. Anyway, I am getting Logan neutered next week. I am worried sick though. I know parvo is hard on their immune system and still if they get a scrape or cut it takes a while for it to heal. My question is, Is it safe to neuter him and put him through all of that? After all we went through with the parvo its scary to think something could go wrong. Maybe I am crazy and just making a big deal out of nothing but I can't help it.
