For those wondering what car seat it is, etc, here is the link to Overstock.com:
Pet Gear Medium Booster Car Seat (Interior Measures 10" x 14" ) | Overstock.com
It is size Medium, Charcoal color, and it does come with 1 tether to hook to their harness. Overstock has the best price with shipping that I've found and I have been looking at them for a YEAR now. LOL I preferred the charcoal color (Erin, you are so awesome to have picked out the right color! :aktion033

because I figured it would stay a little cooler than the black. The tan is also nice, but one of our cars interior is black and the other car has grey...and I like to match. :thumbsup:
The cover is removeable & can be hand washed, although I had an idea of spraying ScotchGuard on it and that should make anything wipe off even more easily. There is a little cushion in it that also has a removeable cover, and you can take the cushion out if you want them to sit "deeper" in the seat or add your own blankets, etc.
My two weigh approximately 6.5lbs each and they are the perfect size for them to sit or lay in without having extra room to roll around. I once pondered (months ago) whether the medium or large would be better for each dog, and decided the medium is best because they are designed to keep them secure, not to lounge around & stretch out in. If you have a pup that is 10+lbs I would probably get the large. The large also comes with 2 tethers if you have two smaller pups and want them to share. I still think it's safer for each to have their own...and there are no fights about who gets to sit where. lol

The seat sits up high enough so they can see out of the window if they want (I think anyway...I haven't put it in the car yet, but it is a very tall seat).
One of the pups will get to try out their new car seat either today or Monday! :chili:
Preston is due for his regular vaccinations and I also need to take London in for Bordatella because in a few weeks they will be starting their first obedience training class. I choose not to vaccinate them on Bordatella unless they are going to be in a public environment like a grooming salon, dog classes, etc. Maybe one of the dogs can ride in it on the way over, and the other can ride in it on the way back!

Don't worry, the "loose" one will be crated.
I'll let you know how they like their car seat! Inside they love it...during picture time they didn't want to get out of it. LOL
