how can I clip my dogs nails?

He is a 20 lb terrier and has to be put under by my vet.<br />
which is costly and risky. Costs about $55.00 every 4/5 months.<br />

I HAVE 3 LABS FROM 85LBS TO 130LBS, AND I'VE FOUND THE BEST AND SAFEST WAY IS TO USE MY DREMEL WITH A SANDPAPER DRUM ON THE NAILS. IF YOUR DOG BITES MAYBE YOU CAN USE A MUZZLE WHILE YOU DO THIS. IF YOU DON'T HAVE A DREMEL YOU CAN PROBABLY GET ONE FOR LESS THAN THE COST OF CLIPPING

First of all, you should make nail clipping a good moment for him. So, at first, just lift him on a table, and take a look at his paws. (be careful not to drop him). If he lets you handle his paws, tell him he is a good boy and give him treats. Repeat until this goes well. <br />
<br />
Gradually, move towards actual clipping. For example, just clip one nail, and give lots of treats. <br />
<br />
Some people have found out, that nail file works much better than nail clippers. It is easier to do this step-by-step approach with a nail file, and the dog might not be afraid of file, even if he dislikes nail clippers. <br />
<br />
If the dog walks enough on rough terrain like asphalt, you need to clip nails less often. (except those thumps in forelegs)<br />

Remember, baby steps! Do not try to clip nails too early. It may take months!
