If your dog or cat suddenly has a puffed‑up paw, leg, or face, stay calm and act fast. Swelling can be caused by a bite, a bruise, an allergic reaction, or even an insect sting. The goal is to lower the inflammation, keep the pet comfortable, and decide if a vet visit is needed.
First, take a quick look. Is the swelling warm, red, or oozing? Does your pet pant heavily, drool, or seem itchy? A warm, painful lump often means a bite or injury, while a sudden, itchy swelling could point to an allergy. Knowing the trigger helps you choose the right first‑aid step.
If you can safely move the pet, gently feel the area. Press lightly—if it’s tender, avoid squeezing. Note if the swelling is getting bigger within minutes; rapid growth is a red flag that needs a vet right away.
1. Cool it down. Fill a clean bowl with cool (not icy) water and dip a cloth or towel in it. Apply the damp cloth to the swollen spot for 5–10 minutes. This helps shrink blood vessels and eases pain. Do not use ice directly on the skin; it can cause frostbite.
2. Elevate if possible. For swollen legs or paws, gently raise the limb above heart level. You can use a pillow or a folded towel. Elevation reduces fluid buildup and speeds up recovery.
3. Compress lightly. If the swelling is due to a sprain or minor bruising, wrap the area with a soft elastic bandage. Keep it snug but not so tight that it cuts off circulation. Check the toes or paw pads for color changes; pink is good, blue means too tight.
4. Give water. Encourage your pet to drink small amounts of fresh water. Hydration helps the body flush out excess fluid and supports healing.
5. Watch for allergy signs. If you suspect an allergic reaction—hives, wheezing, or trouble breathing—give an antihistamine approved by your vet (often diphenhydramine at 1 mg per pound). Call the vet immediately if breathing gets worse.
After you’ve done the basics, monitor the pet closely for the next 24‑48 hours. Keep the area clean, change the compression bandage daily, and note any changes in size, color, or behavior.
Even if the swelling seems mild, you should call the vet if you notice any of these:
These symptoms often mean the underlying issue needs professional treatment—like antibiotics, stitches, or emergency allergy care.
Having a pet first‑aid kit at home makes it easier to act fast. Include a cold pack, sterile gauze, elastic bandages, tweezers for splinters, and your vet’s emergency phone number. A few minutes of preparation can save a lot of worry later.
Remember, quick, calm action can make a big difference. Use the cooling, elevation, and compression steps to soothe the swelling, and don’t hesitate to reach out to your vet when something feels off. Your pet’s comfort and safety are worth the extra effort.
