I have a Rav4 and same problem. Can't use the back seat as we have 2 children. The buggy bit of the pram fits in upright with the dog next to it but until baby is in that without the carry cot the dog is staying at home unless we take 2 cars!! Considering getting a crate for my husband's estate to separate dog and pram but he isn't keen.
We only have one dog (28kg) and a VW Golf, buggy takes up whole boot. Dog used to be harnessed into one side of back seat and baby's car seat was in the front seat (for reasons not relating to the dog). You'll need a preeeetty big boot to fit two Labradors and even just a buggy chassis. We end up taking two cars now that ds is in the back seat.
I think you'd be hard-pushed to find a way of getting two large dogs and a buggy in the boot of any car tbh! We have two 10kg Spaniels and they will be harnessed into the backseat when baby arrives in 2 weeks. They are in a crate in the boot at the moment but we still can't fit the pram chassis in beside it (and it's an SUV so fairly big boot). I don't imagine we will have both dogs and pram in the car at the same time very often though, so I'm not too concerned.
Would a roof box work? My Dad always had one for our cars growing up. I know you also get boot separators so you could have half for pram and half for dogs, but not sure if that would be too tight for two Labs?
Hmmm heres hoping me and baby master the art of carrying which I plan to for dog walking anyway as we walk very rural. I guess the main times I will need a Pram and dogs will be when visiting our parents (both big journeys away). Dogs always come with us. Was chatting to OH last night he has a big work transit and he said we could get a crate for inside the van and then space isnt an issue in there and maybe use that if we need to go out with a pram and dogs.
You can get a dog guard which goes down the middle of the boot to split it into two sections (size adjustable) so dogs on one side buggy on the other. A lie flat buggy will probably take least room as no separate seat/cot unit
Just get a buggy that will fit behind the front seats in the footwell and don't bother with a carrycot. So long as the buggy goes flat it will be fine. I wouldn't want to put the buggy in a boot full of dog hair anyway!
My plan is dog harnessed on front seat, baby in the back and pram in the boot when there is just one adult in the car. It's where he usually rides now and I like that I can keep an eye on him with the baby in the car; when my DH is with us either him or the dog will be in the back but there will be another adult to keep an eye on the dog baby situation.
