Make sure you have a way for them to drink water in the car
The easiest way is to get one of those things that sometimes newborn puppies drink from, or rabbits...
they have special ones for dogs
just teach them how to drink from it before you go
Because we just have Tila, we've always had a cup of water in the car
and she drinks from that
but it gets her mouth ALL WET
You want to keep her microchip information on you
(if she has one)
because if she goes missing...
(she probably wont)
you want that information
and I also suggest always keeping a harness on them in a car
and a leash handy
(i keep a leash in my back pocket no matter where I am with Tila)
I suggest she always wears her tags on her collar
I'd take a crate, for her to stay in when you aren't in the hotel room
(a lot of hotels people go in the rooms regardless of the signs)
Just to be saaafe!
Also who's gonna be in the car ride
just 2 people?
it might be easier for one to sit in the backseat with her,
take some toys for her, and a blanket that she likes
(if she's into that)
that's all kind of given
but if you're going to be in the car for a LONG time
she'll be more comfortable in the back seat!
anyways this is a lot of stuff so I'm gonna shut up now ha ha
