Before you set out to trim your pup's fur for the first
time, you must be sure that his coat is actually ready to be cut. If you cut
his coat too soon, you are cutting it before his primary hairs have had a
chance to grow in. Puppies like Jimmy are born with short, fluffy hair, but by the
time they reach six to eight months old, their adult coat should have grown in. If
you trim his hair too soon, this could have a negative impact on how well his
permanent coat develops. Beyond that, trimming around his eyes and muzzle may be
necessary, but don't be in a rush to trim his body hair.
Keeping a puppy's fur trim can help keep him clean, but only if the trimming is necessary. Consulting a veterinarian or a professional groomer on whether or not you are able to trim Jimmy's fur is a good first step.
Jimmy is far too young to really care if his coat is perfectly trimmed. His only real interests are food, fun, and going potty. Once his adult coat has grown in and is ready to groom, the process is very similar to the one you would use for adult dogs. The biggest difference is that Jimmy is going to be wound up like an eight-day clock. The methods used are very similar to those you would use for any excited dog.
The hardest part of trimming puppy fur is working with a pup who can't or won't stop wiggling. Plenty of exercise and a nice, warm bath are good ways to relax Jimmy and put him in the mood to be groomed. If he doesn't, you may need the help of an assistant until he gets used to being trimmed. Never be afraid to use treats to get Jimmy to behave while you are working.
