When your pup's nails get too long, there is more to the problem than them being unsightly. Nails that have been allowed to grow too long can make walking very painful, as at each step the nails are putting excessive pressure on his toes, often twisting them badly. Imagine what it would be like if you had to walk around like that every day. The extra pressure on his joints can put too much pressure on his joints as well, leading to injury and permanent damage. This is especially important with larger dogs whose feet have so much more weight to support.
The last thing your pup wants is to have no choice but to walk around on his nails instead of the pads under his feet. Your pup is not going to like having his nails trimmed at first, but with time, he will get used to it and may even look forward to it. It's easy to tell when your dog's nails start to get too long. He will spend more time laying around, and you can usually hear them clicking on the floor.
The best thing you can do while you are getting your pup used to having his nails trimmed is to take your time and let your pup get used to what is going on. It is important for you to keep his nails trimmed on a regular basis. Long nails can cause permanent damage to your pup's feet, legs, and hips, they can also cause an amazing amount of damage to your flooring and carpets. Use plenty of treats as rewards and make the whole process fun for both of you.
