Boo will be in the 3rd row, outboard passenger side. Nobody else (due to not wanting a RF seat back there, and there not being any more tethers).
I don't feel comfortable with a dog sitting beside him all the time. It would likely be okay if it were Bo,
but Pugs and Boo don't mesh so well. Hard to explain - I don't think either of the dogs or Boo would be in danger if one of the dogs was beside Boo, but I don't like it.
Perhaps one dog crated in the far back and the other to a seat leg bracket? Both dogs inside a crate together? Or one along side crated & a crate in the back?
I understand perfectly why you don't want your dog(s) & child alone all the way back there. Crating would protect everyone. Could always put a towel over to keep fingers where fingers belong.
I don't know if it's possible seeing their sizes, but those are the suggestion I can think of..
The way I look at it (a bit harshly, perhaps) --securing the dogs are not really to prevent any harm to them during an accident, but to keep them from flying around hitting people & windows. Along with the major desire to keep them
INSIDE the vehicle if a door/hatch pops open or a 'rescuer' opens the door to the outside. I'd say that more dogs are hit or injured after the accidents from running loose than during the collision.
The safest thing for the pets is to remain inside vehicle and secure anyone from their distress where they might fear bite/attack.
good luck. Wish I could help more.
