Collar fit is really important. Too tight, and it could hurt. Too loose, and all of a sudden your pet is on the run halfway across the park. For a collar that stays put comfortably, you should be able to fit two fingers underneath but not slide it off easily. In case of emergency, both dog and cat collars should have an ID with your phone number on it.
If your pet is constantly trying to slip out of their collar or tugging on walks, you have a couple options. To prevent choking and discomfort, you can simply switch to a harness. But if your dog is especially stubborn, you may need collars or harnesses that help with training. A Martingale collar is made up of two loops—one that stays loose and comfortable, and another that tightens a bit (without hurting your dog) to correct behavior when they pull on the leash. The other choice is a head collar, which goes behind the ears and around the muzzle to minimize their ability to pull with their head. Both of these need to be fit properly and used carefully (and we’re happy to help). That being said, there are definitely control collars that we don’t stand behind, such as ones that choke, pinch, and shock. Hurting your pet is not a great way to communicate and is also just plain mean.
For more mellow pets who’ve mastered leash training, there’s always a simple buckle collar. It adjusts like a belt and is meant to stay on all the time, inside and out. And for our feline friends who spend more time at home than on leashes, there’s breakaway collars, which come apart when pressure is added (such as when they get snagged on something while performing a death-defying cat feat). However, if you’re experimenting with walking your cat (yes, you can do that), always put them in a harness rather than a collar.
