Long toe nails can be very painful.  Keep them in shape and your dog will be more comfortable.

Trim your pets nail or take them to a groomer to have them trimmed. 

I tried to take him to the vet for a trimming but the vet wanted to charge too much.  I found a local groomer who took walk in nail trimming.

If you attempt to trim your dog's nails, be very aware that you are entering a world of pain for dogs. Just one clip too close to the vein and the pain is unbearable.

Have your vet or groomer show you how to trim the nails. Most of the time they are generous with their tips because they know you will be more likely to come back to that nice groomer's.

I would also just show up at the Groomers at an off time before you make the appointment.

Take a notice to how the groomers are treating their dogs.

I once caught a Groomer (who seemed to be mad at the world) yanking out huge clumps of matted hair while this little Maltese cried and cried.

Would you want your dog to be treated like that? Be safe, rather than dissapointed and check out the Groomers first.
