Ok I feel like a bad mommy but I just recently discovered that it's dangerous to use a collar when walking Chihuahuas so I went and got Chico a new harness, which looks great on him, but he hates it. He used to love going for walks but now every time I put him down to walk on the leashe he just jumps on my legs and gives me his special squeak-bark and begs me to pick him up. I have been leaving it on him to try and help him get used to it and he doesn't seem to mind it when the leash is not on it but when I put the leash on him he just wants to be held. I even tried taking him to the pet store, which he loves, but he still just wanted to be held. Any suggestions?
