Hi..sounds like great fun for chaos! And glad you found a vet you like! There are people here who swear the nasal spray version of the bortadella vaccine contributes to pneumonia. No such issues with the actual shot tho. My vet gives the nasal spray and she sees tons of bullies..and she OWNS one too. I gave the nasal one to Jake with no side effects..but I'm sure there is disagreement here! I'd just watch ..like every time they get a vaccine. Chaos looks beautiful!
