Ah, the great collar versus harness debate! The answer really comes down to your dog's behavior, breed, and health.

Collars are simple, convenient, and perfect for dogs who don't pull on their leash or have respiratory issues. But if your dog is a natural-born explorer who loves to lead the way (and by that, I mean pull!), then a harness may be a better choice. Harnesses provide more control and distribute pressure across the chest instead of the neck, which can be safer for your canine companion.

As for leashes, they're not just for control - they're a safety tool too. They keep your dog close in unfamiliar environments or near roads. However, it's also essential for dogs to have some off-leash time in safe, enclosed areas for free play and exercise.

So, no, it's not bad for them to always walk with leashes, but balance is key. Think of it as wearing a seatbelt in a car – necessary for safety but you won't wear it while chilling at home!
