Ensuring your dog collar fits just right is vital for their comfort and safety. Use the "two-finger rule" to check tightness: slip two fingers between the collar and your dog's neck. If they fit snugly without being too tight, it's perfect. The collar should stay in place without slipping off, allowing your furry friend to breathe and move comfortably. Avoid over-tightening, as it may cause discomfort or breathing difficulties. Regularly check the fit, especially during growth or with a new collar style. A well-fitted collar enhances enjoyable walks and activities, promoting your dog's well-being.
