HOW TO TRIM YOUR DOG'S NAILS
Start by getting some nail trimmers. Be carful trimming your dog's nails. There's something called the quick. Its a pink line you see on your dog's nails. DO NOT CUT THAT OR YOUR DOG WILL BLEED. Trim your dog's nails gently. Be nice and calm to your dog. I
f the dog freaks out, say 'ah-ah' and continue. If the dog still doesn't calm down, give him a treat and praise and try again later. If your dog did good, give him a treat and praise. Whenever your dog's nails are too long, trim them. If you did accidentally cut the quick, it's ok.
You should apply firm pressure with a towel, or better yet apply a powder solution called 'QUICK STOP".
Don't feel bad, i've done it before. Dogs that get overgrown nails can get them embedded in their paws and that is extremely painful and uncomfortable. If this happens your dog will need to have surgery.
