Well I can tell you this, Dogs nails should be done at minimum every 4 to 6 weeks.
Waiting longer causes the nail to grow out, and turn around and dig into the pads of the dog. Pulling the nail out after trimming, leaves and open wound in the pad of your dog. It causes the dogs toe to twist to the side, causing pain as they walk, and malformation of the foot. The nail can get hung on a number of things and rip off, breaking the quick, which causes bleeding, most likely all over your house, or car. If the quick is ripped open from a broken nail, Infection is a high possibility, as it is no different than you getting a cut, except they walk around on dirt, etc, so particals can work their way into the bloodstream and cause an infection.
Also the second problem with waiting to trim nails, is the quick grows as the nail grows. So every time you have your dogs nails done, they have to be cut longer and longer. Which means over a period of a few years, even when the nails are trimmed they are still a hazzard for your beloved baby. The longer the nail is, the better chance they have of catching the nail on something.
Some dogs do wear off their nails, more active dogs, that walk alot on pavement can go longer between nail trims. Just because you walk your dog on pavement though doesn't mean they dont need to have their nails trimmed. Some dogs nails are higher on the foot, so they don't get ground down as they are walking/running.
