Understanding the dog-cat chemistry

It sounds like the dog just wants to play using his prey drive (stalk, chase, etc). First, do not punish the dog when he does this because he will associate this with the cat and it will make matters worse. This situation calls for more exercise for the dog (including play that allows him to use his prey drive) and careful management of the dog and cat. Start implementing the 'Nothing in life is free' routine immediately. Continue rewarding the dog for ignoring the cat and interacting politely. You can interrupt the dog with an "AH AH" when he starts to focus on or play with the cat and redirect him to something that's even more fun (tug, fetch etc). Until you can learn to trust him you will have to supervise them.

Never try to cut a dog's toenails at home. You should go to a professional. The general rule of thumb is to clip where the nail makes a defined curve down towards the floor. Don't cut too far beyond that or you will snip the quick. Keep in mind that the longer you allow the nails to grow, the longer the quick may grow, as well. If you cut too far, it will cause pain and bleeding. The easiest and most effective way to stop dog nail bleeding is with styptic powder or a styptic pencil, which can be purchased at most pet stores and pharmacies. Be cautioned, however, that styptic powder will provide an initial sting, so be prepared to hold onto the dog firmly while applying.

Several home remedies also work, depending on the severity of the bleeding. A mix of corn starch and baking soda often works well , while rubbing a clean bar of scent-free soap or a wet tea bag on the nail at the spot of lesser bleeding can also be effective. No home remedy, however, will be as instantly effective as styptic powder. Also keep a clean cloth, paper towels and ice nearby.

If you accidentally cut into the quick, immediately compress the wound for at least two minutes with a clean cloth or paper towel. If the bleeding is minor, try rubbing a bar of clean, scent-free soap over it. If the bleeding is steady, wrapping ice within the compressed cloth or paper towel will help lessen the blood flow. Next cup your hand and pour some styptic powder or corn starch (with or without baking soda) into the palm. Gently dip the dog's bleeding nail into the powder, repeating if the bleeding doesn't come to an immediate stop. Don't wipe away the blood before dipping because it will aid coagulation. Once bleeding does cease, continue to compress the wound with a paper towel or cloth, being cautious not to squeeze the paw. Try to keep the dog off his feet for at least 30 minutes.

Once you are sure that the dog's nail bleeding has been stopped, wash the affected nail with lukewarm water and bandage it to prevent licking and infection. If bleeding cannot be controlled after 20 – 30 minutes, proper clotting is not taking place and a veterinarian should be consulted immediately. Also consult a vet if the dog's toe later becomes red, swollen or does not appear to be improving after a few days.
