Ezydog Drive Dog Car Harness - Crash Tested & FMVSS 213 Certified Adjustable Pet Seat Belt for Safe Travel - Padded Comfort Medium Dog Harness - Perfect for Road Trips & Daily Car Rides with Your Pet

I use this car harness for my (Medical Alert + Response) Service Dog and have convinced several of my friends to get one for their service dog. Once properly fitted, it is super easy to get your dog in and out of it which is important for me because my dog wears this harness in the car and then every time we get out of the car, I to switch him into his service dog vest.I did a lot of research when choosing a car harness so allow me to save you some time and energy. Sleepy pod (the only alternative worth considering) brags about being the making the only two car harnesses approved by the Center for Pet Safety for dogs over 25 pounds. However, this harness was first introduced after the last round of testing the CPS conducted (7 years ago). I have not only watched the videos of the crash testing EZ Dog had done for this harness, I have involuntarily put this harness to the test myself on multiple occasions. The first time was when I had to slam on the brakes while going 45 mph thanks to a cat darting across a busy street in a commercial area. Despite being able to transition from seated to laying down at will, my dog didn’t move an inch when I had to slam on the brakes. The fact that I was a bit shaken after the fact seemed to be the only part of the experience my dog actually registered. The other testing was courtesy of LA freeways’ 75 to 0 mph stop-and-start rush hour traffic and a couple of drivers weaving (without using blinkers/turning signals) in and out of traffic while going 90+ mph and cutting people off. The only part of those experiences my dog seemed to register was my complaints and “choice words”.I ended up choosing this harness over the Sleepy Pod options because of the ability to customize the fit of this harness. Both this harness and the Sleepy Pod options protect your dog *when fitted properly*. Improper fit was the top complaint of reviewers of both of the sleepy pod options. If you feel that this harness does not properly fit your dog, you are probably using it incorrectly. Before you start adjusting straps, I recommend holding the chest plate up to your dog so that it is molded to his/her chest as seen in product photos and then adjust the straps to keep the chest plate in that position.A note about durability: part of what makes this harness so safe is that the adjustable straps are made of seat belt material. Seat belt material is what cars, planes, roller coasters and more use to keep people in motion safe. Should they have the will and opportunity to do so, most dogs can chew through a seatbelt, but seatbelts are still the standard for safety. It makes no sense for the makers of any car harness to compromise the safety of a harness to make it chew proof when chewing on its own harness, leash, etc. is an undesired dog behavior that is eliminated with training and in the case of puppies, maturity. When introducing your dog to this (or any) harness, create positive associations. Put the harness on your dog, do one of your dog’s favorite activities and give treats, then take it off. Drive a lap around the block with the windows down then go home and give a kong. If the only time you use a particular harness or vest is when you bring your dog to the vet, groomer, or to do something they don’t want to do, they will want nothing to do with that vest or harness and are more likely to attempt to chew themselves free.I hope this helps anyone considering a car harness. Thank you EZ Dog for being a life saver for my little life saver!
