Precautions:
1, according to the width of the dog's neck, choose a suitable length collar for it. After wearing the collar, the dog should be comfortable and can't get caught. Don't fasten the collar too tightly. After fastening the collar, you should be able to easily insert two fingers.
2. The puppy should take off its collar when it is unattended, so as not to be caught by other things and cause suffocation. It is best for long-haired dogs not to wear collars for a long time, so as to avoid the hair on their necks being compressed, losing their original sense of richness and affecting their aesthetic feeling. Dogs with fragile and sensitive trachea had better not use a collar when they go out, because the collar will press the trachea when the puppy suddenly moves forward.
3. Collar is a kind of leash with the most patterns, besides being used to take dogs out for decoration. There are even gold and silver necklaces inlaid with jewels abroad to show the owner's wealth and status.
