Here is your Behavior & Training Tip from HelpingFido.com 

Are nail trims a nightmare for your Fido?  It needn't be that way.  If you have a puppy or young dog, start NOW with the acclimation procedures in this tip or enroll your puppy in a class that includes nail trim exercises.

If your adult dog is a nail trim terror, get to work ASAP and be patient - his problem didn't develop in one setting and it won't be 'fixed' in just one either.  But there's no time like the present.  Turn up your speakers and listen up!

Best of luck from Dan and Suzanne
