well my dogs a a million differnt collars, harnesses and halters lol Ripley ALWAYS wears a tight fitting collar. period. he is a master escape artist, and while he no longer takes off out doors are slips through the gate, people DO open our side gate sometimes, whilke I had the gate locked for a while, our front door died(it no longer opens at all, my brother or I have to lean out the window to bring in the mail and newspaper lol) so my brother had to go back to useing the side gate. for flyball he has a tight none tagged collar. he actually wears it all the times right now as his tagged collar broke and none of our other collars fit him properly.

Misty has her tagged smily face collar wich she wears most of the time, tightly, she always wears a collar not because she goes anywhere, she wont leave the yard with the gate standing wide open lol but because Perky and Blair like to provoke her to fight, and we need to be able to grab her easy. she also has several un-tagged collars, a harness and a halti, and she wears a clipped up chain collar(I added a clasp to a training collar,so it works like a martingale) when I want to give her hair time to grow in properly.

Happy sometimes wera s a collar and sometimes does'nt, latly she has been though as the summer games are going on near my house, and well sports gets Happy rearing to go play with them lol otherwise she does not wear a collar at all, its not like she is going to run away, she wont even leave my side lol

Blair and Perky always wear their collars, Perky because she looks weird without one, but she also has decorated collars for freestyle, Blair has no tags but he is a brat and we gotta be able to grab him somehow, my mom always complains when I take his collar off lol they both wears then tight enugh to slip 2 fingers in.
