My dog has extreme crate fear he makes him extremely visous and he attacks everyone and everything, so getting this was a godsend. The vet said I had to do something different or they wouldn't be able to treat him anymore. I used this seatbelt system the next time I took him to the vet and when we got there his tail was wagging I was in a state of shock that being in a crate for 5 minutes could upset him that much. This will now be my go to solution for travling as before sedation was the only answer which I hated doing because he would pee himself and it smelled all the way to where we were going. I am so grateful for this product it's well made and sturdy and I know Whiskers will use it for years to come.
