The best way to keep floors clean is to never let them get dirty. And that means catching those muddy paws before they come inside. Here are some tips: Use mats. Put washable mats both inside and outside the door. A small door mat can be jumped over, so go for something larger, at least during the rainy season. The wider the area of matting, the more chance you have of every paw hitting the mat at least once. Try a 3-foot-by-5-foot black industrial mat on either side of the door: It catches lots of mud and hoses off easily outside.

Teach dogs to wait for wiping. It's not difficult to teach a dog to wait on the mat for a paw cleaning. If you're patient and positive, you'll be able to teach your pet to offer each paw in turn and stand patiently while you towel it off.

Save your old towels. When towels get too ratty for guests to see, save them for use with your pets. Old towels may be ugly, but they are great for wiping paws, drying fur and even swiping a muddy paw print off the floor. You can also find super-absorbent towels and mitts made specifically for wiping paws. If you do need to buy paw wipes, then check prices on shop towels.

Never let a mess settle in. If a muddy paw gets past you, don't delay your cleanup. While this isn't such a hard-and-fast rule for such easy-clean surfaces as tile and hardwoods, it's an absolute commandment when it comes to carpets. Keep cleaning supplies well-stocked and at hand, and be sure to jump on a muddy paw print -- or any pet mess -- before it can set. --

Just as with human medicine, advancements in the way we think of and treat pain for animals is improving the quality of life for pets, with veterinarians now being able to choose from a wide array of products and strategies to ease the hurt.

"Animals can feel all the same aches and pains that we can because they share the same physiologic structures."

Treating pain doesn't just make the hurting stop: It also promotes healthy healing. Untreated pain slows healing time, interferes with sleep and depresses the immune system. The treatment of pain improves respiration, shortens post-surgical hospitalization times, improves mobility, and can even decrease the spread of cancer after surgery.

Most veterinarians prescribe pain medication when needed, but some still believe a pet will move around less during recovery from surgery or injury if in pain -- a belief no longer supported by studies. If an animal needs to be restrained, it's better to use a leash or a crate.

Still, many owners don't give pets pain medications -- even if they are prescribed -- because of concerns about side effects. All drugs can cause unwanted effects, but those risks need to be balanced against the problems caused by untreated pain. Side effects can also be minimized by using drugs appropriately.

The family of drugs known as NSAIDs (non-steroidal anti-inflammatory drugs) can cause ulcers and damage the kidneys in pets, just as they can in humans. But in the same way that people continue to use these drugs for everything from headaches to back injuries, NSAIDs have a valuable role to play in the management of animal pain.

When NSAIDs are needed, it's essential to follow label recommendations for veterinary testing and monitoring of liver and kidney function. Pet owners should review all potential side effects with the veterinarian and stop giving the drug immediately if vomiting or lethargy is observed, or if the pet stops showing interest in eating. Pain-management experts also suggest asking the veterinarian about the human drugs misoprostol and sulcrafate, which can help protect the stomach lining and prevent ulcers. For dogs, the prescription of Tramadol has been on the increase, and many dogs unable to tolerate NSAIDs have benefited. Tramadol can also be used with NSAIDs and can be taken with steroids, which NSAIDs cannot.

Complementary and alternative medicine also has much to offer dogs and cats suffering from chronic pain. Acupuncture, physical therapy and supplements such as glucosamine and chondroitin can relieve arthritis pain. The veterinary drug Adequan Canine, an injectable relative of glucosamine, can target inflamed joints and help rebuild cartilage.

Some dogs and cats, such as those with certain kinds of cancer, need the powerful pain relief that only opiates can provide. Owners often dislike these drugs because they make pets groggy. Fortunately, if long-term use is necessary, the sedation effect usually lessens after a few days.

Opiates can also cause nausea and lack of appetite. A bit of catnip often takes care of this for feline patients, while peppermint or ginger -- even in the form of a gingersnap -- can make a dog feel better. There are also prescription medications that can help control nausea.

Downing is one of just a handful of veterinarians worldwide credentialed in human medicine's American Academy of Pain Management, as well as being a certified veterinary acupuncturist and physiotherapist. Her approach to pain takes into account the pet's lifestyle and family issues as well as the actual source of the pain.

"I certainly leverage all the tools I can for fighting pain," Downing says. "But my long-term strategy is always maximum comfort and mobility with minimum negative impact on the body. We rely on physical medicine techniques, adapted from human medicine, to complement what we accomplish with medication as well as nutrition."

Pain control is never a "one size fits all" prescription, and there are dozens of drugs that can be used alone and with other medications to relieve all but the most extreme pain in animals. When a veterinarian isn't sure how to get to the bottom of a pet's pain, it's always worth asking for a consultation with a specialist to design a safe, individualized pain-management program. Veterinary specialists in oncology, surgery and anesthesia are usually most familiar with the wide variety of drugs available today and their safe use.
