Before I start out on my long trip tomorrow to get Brodi, I'm curious about him peeing. We have about a 5 hr drive back home and I'm worried about where to let him go potty. I don't want to put him on the ground to go due to him not being fully vaccinated yet against parvo. Am I right on this one or no? It's been almost 3 years since Chloe's puppy days so I wanted to make sure. I remember not letting Chloe out of my arms even at the vet's until she was fully protected. Any idea's on where to let him go??? My SUV seats lay flat down in the back so I was thinking of a piece of plastic to lay down with some newspapers..His breeder said he is about 90% paper trained..Any other idea's???
