Hey guys! I've got two dogs I hike/camp/everything with. Roughly 40lbs ish.(Photo attached. Sasha is the orange one and Dipstick is the black one.)Dippy and SashDippy and Sash I should hope to never need to use it, but does anyone know of something to carry my dog back to the car should one of them be injured? 
I found one thing that is supposed to do so, but it's also $200+ and I don't have that kind of money. I also, however, would rather be safe than sorry and have something should I need it. 

Any assistance would be much appreciated. Thank you all!
