Hi, here are some of my opinion that may help you out.
Dogs should not bite at their nails to “trim” or “shorten” them. If your dog is biting at a single nail or multiple nails, he or she is most likely itchy around the nails.
Trauma to nails may happen in various forms—human error during nail clipping (too close to the nail bed) can lead to problems.
Be gentle and careful while trimming dog nails. Learn the correct technique from your veterinary technician or groomer, if needed.
For black nails, it is tough to ascertain the length a nail should be trimmed. Trim conservatively if in doubt, or trust your groomer with the nail trimming.
Indoor dogs and dogs that walk only on soft surfaces may have longer nails due to less wear on the nails.
Don’t forget the dewclaw nail (the nail higher up on the paw similar to our thumb). Also check and regularly trim this nail.
Handle your dog’s paws often and check for nail health and foreign material (grass, twigs, tar, etc.) in paw hairs will help you keep on top of good pedal health for your dog. Check your pet’s paws at least 1-2 times a week. This also helps your dog trust you in case if you need to evaluate his or her paws, in case of a problem.
