@brave_heart We rescued a puppy and planned a trip to take place after she had been vaccinated/settled in. This trip involved a small road trip with about a day in the car. Her adoption day got delayed because she was hospitalized at the shelter and it would have resulted in her going on a trip after less than a week of coming home. We decided to reschedule our trip and it was a great decision.
Of course, it gave her time to recuperate, get well, and receive her vaccinations, but it also gave her time to settle in with us and work on training. Thanks to her being a little older and not needing constant potty breaks, the car ride was great. She slept pretty much the entire time and was able to actually go out and adventure when we took breaks since her vaccines were up to date. Her being older also made it to where we could get her on flea and tick preventative which, in my opinion, is absolutely integral if you plan to take a pup on walks or hikes of any kind. Tick born diseases are not only not fun for your pup, but identification and treatment can be pretty expensive.
Aside from health and physical comfort concerns, I think the extra 1:1 time with us and our home also helped her gain some confidence to meet and love our family that she met, and their dogs too!
