Collars are best used for ID tags and for dogs that are well-trained on leash manners. However, if your boxer is still learning to walk nicely on a leash or tends to pull, a harness is usually a better option. Harnesses distribute pressure across the dog's body, reducing strain on the neck and throat, which is particularly important for boxers due to their brachycephalic (short-muzzled) structure.
If you decide to use a collar, ensure it fits properly (not too tight or too loose) and is made of durable material. You might also consider a martingale collar, which tightens slightly when the dog pulls but does not choke.
In summary, while collars can be used, a harness is generally recommended for boxers, especially during training or if they have a tendency to pull on the leash.
