Even though they stay bundled up in their own fur coats, your pets can feel the chilly effects of winter weather. During the cold months, it's important to spend a little extra time helping your pets stay healthy, says Arden Moore, a nationally known pet expert and author of Happy Dog, Happy You (Storey Publishing, 2008).

Here are a few of her favorite suggestions:

• Know your dog's limits. A dog's cold tolerance depends on factors including age, size, and type of fur. If it's 25 degrees, a healthy adult dog with thick fur should comfortably be able to walk outside for up to 20 minutes. At that temperature, however, dogs in their senior years shouldn't stay outside for more than 10 minutes. And small dogs or those with thin coats may need to wear a doggy coat or sweater before heading outdoors if the temperature is below 40 degrees.
   
• Keep an eye on your dog. If he starts to shiver, it means the same thing as if you were shivering - it's time to come inside!
   
• Protect your dog's feet. If you use salt on your driveway to melt ice - or you're walking on salted streets - smear petroleum jelly on your dog's feet before you venture outdoors. This will keep the salt from causing pain in any abrasions or irritations she may have on her feet. Keep a towel handy near your door to wipe off her feet before going inside.
   
• Buy a supportive bed. Dogs and cats who are older or have arthritis will appreciate an orthopedic pet bed, which provides added support during cold, clammy months when they may feel more achy. You can find these beds for about $50 or less online and in pet-supply stores.
