Grooming your large dog's legs can present certain challenges, depending on the breed of your dog. Most dogs with shorter leg hair require very little in the way of special grooming beyond a good bath from time to time. No, it’s the long-haired breeds that seem to need constant attention. Thankfully, grooming their legs really isn't that hard, but it needs to be done on a regular basis in order to avoid mats and tangles.
No matter what grooming method you choose, you should start out by combing or brushing out the hair on your dog's legs.
The last thing your dog wants is you messing around with his legs and paws with shears or clippers. The mere sight and sound of them probably make him nervous. But since he can't exactly keep his own leg hair trimmed, this is a job you are going to have to do yourself. Just remember, the calmer and more relaxed you are, the more your dog will pick up on these vibes and behave in a similar fashion.
There is no reason why you should keep on spending so much money to take your dog to the professional groomer. With a little patience and practice, you can master this simple task. Think of it as a way for the two of you to spend time together. Have fun and don't let on to anyone just how much you and your dog are enjoying yourselves.
