I don't think there is any way you can prevent a dog from catching it... if they put their mouth on a hog, they can get it.
agreed.
If they do get it a $20 bottle of MMS from jimhumble.is will fix it if administered properly, works on parvo to fyi. This is first hand info. Dont believe the propaganda against it, big $$ has a way of demonizing cheap things anyone can use, works great in chicken water to when they get a virus etc
I gave my dog 20 drops twice a day via syringe, when pups get parvo I used 4 -8 drops every 4 hours for a few days
