When my dog princess was about 4 months old she caught parvo. I didnt know she had it, I just thought she was sick because earlier that morning she took the uncooked meat off the stove. So I just waited it out until the next day. She was still throwing up and she wasnt eating right. I decided to take her to the vet and I found out she had parvo. I got her the medication and the vet gave her the I.V. From there on I gave her antibotics. I also force fed her water. Then when she stopped throwing up I force fed her pediasure mixed with wet dog food.
