Ruger developed a small abscess on his tummy (I'll spare you the pictures) and had to go to the vet. They drained it, he started antibiotics, and we received strict orders that he or Nash could NOT lick it. We had a choice between making him wear an e-collar or a onesie. This is what we chose. :)
Update to a few days later: puppy onesies don't hold up well to wrestling with your brother in the yard
