The only problem with having people come over to dogsit in our place is that the house belongs actually to my parents in law, and they actually live there half the time. They do not like to have strangers in the house while no one is there.
My best option so far is to have them boarded at someone else's home, who has no existing dogs, but yet is willing to take on an unfriendly dog. The other option would be to put Natsu with a nice home boarder, and Kobe in a kennel - where he would be miserable I'm sure.... I need to find something which works!
The protocol which the vet recommended on the phone was DHPPi (Distemper, Adenovirus, Parvovirus + Parainfluenza) once every 2 years (why not 3! since I don't see any authorised dog vaccines which are 2 year duration and the Parainfluenza part of the vaccine is only valid for 1 year), and lepto every year.
I need to discuss titers with the vet more. He did tell me that it was possible to do titers for DHP but Lepto and Parainfluenza are not testable using the usual serology testing. Then I need to check whether the boarder would accept this - definitely worth a try though!
I hate it that I have to put my dogs through this...
