Why is it so important to make sure your your pups nails are trimmed? Now lets get into if your pup is more always inside or active outside with you? If they are active and get lots of walks or run with you and such then they more than likely will wear down themselves and naturally and may on need a touch up with a dermal. If you leave them untrimmed and let them grow in extreme cases they can curl under and get embedded into their paws. If they chip or break this may cause extreme pain and possible infection. There are many ways to trim nails but I prefer the dermal. For me clippers can be tricky and you may quick the dogs nails to short which contains blood vessels and nerves. In most cases most people go to their local groomer or their Vet to get It professionally done.
