I bought a Guinea Pig Harness for my Tegu, Mike. It fits him perfectly, I tried it on inside and I had no problem with it. It's safe, not too tight, and he can't get out if it ('Cuz I tried one for cats before and that doesn't work!)
The thing is, when I bring him outside, he freaks out! He runs everywhere (really really fast) so I was wondering if there's a way to get him used to the leash and harness? I know it's not a dog or a cat, but I'd like him to go outside once in a while ('cuz we bring our snakes out too). So, is there a way? Thanks!
