Swollen dog paws are mainly caused by bacterial and fungal infections, parasitic infections, allergies, toe fractures, scratches on the paws by foreign objects, paw burns, excessively long dog nails, tumors, etc. When a dog's paws are swollen, it can also be difficult for the dog to walk, so he or she will often walk with a limp. The dog will still feel obvious pain when the owner touches its feet, so it is recommended that the owner take the dog to the doctor in time.

1. Bacterial and fungal infections

If the dog lives in a relatively humid environment for a long time, or does not dry the dog's paws in time on rainy days, bathing, etc., it may cause paw infection. Bacteria and fungi proliferate, causing inflammation and swelling. Therefore, the owner must ensure that the dog's living environment is dry and clean. On rainy days or after bathing the dog, the owner must promptly dry the dog's feet or blow dry the paws.

2. Parasitic infection

When a dog is infected with parasites such as mites and ticks, these parasites may bite the dog's paws, causing swelling. Therefore, owners must deworm their dogs regularly and disinfect the environment where their dogs live once a week to prevent parasitic infections.

3. Allergy

Dog allergies can also cause swelling of the dog's paws. In addition, the dog's paws may also become red, inflamed, itchy and other symptoms. If this is the case, be sure to take your dog to the pet hospital for desensitization injections as soon as possible and investigate the factors causing the dog's allergies.

4. Broken toes

A broken toe in a dog can also cause swelling of the paw, such as being stepped on by the owner, hit by a heavy object, jumping from a high place, or getting stuck on a railing. , car accidents, etc., may cause the dog's toes to be broken and the claws to swell. In this case, you need to take your dog to the pet hospital for examination and treatment as soon as possible.

5. The paw is scratched by a foreign object

6. Paw burns

In hot summer, the temperature of the road is often much higher than the actual temperature, which can easily burn the dog's paws and cause swelling. Therefore, it is recommended that owners do not take their dogs out for a walk at noon in the summer, otherwise the dog’s paws may be burned or suffer from heat stroke.

7. Dog nails are too long

When a dog’s nails are too long, it will seriously affect the dog’s walking, causing the dog to walk unsteadily, and the nails may bend due to the pressure exerted by the ground and dig into the dog’s flesh. This can cause the paw to swell, bleed, or even become inflamed. Therefore, owners must trim their dogs’ nails regularly to avoid excessively long nails.

8. Tumors

In rare cases, swelling of a dog’s paws is also caused by tumors. Some malignant tumors often appear between dogs' toes, such as melanoma and squamous cell carcinoma. At the same time, some breeds of dogs are also susceptible to melanoma, such as dogs, dachshunds, golden retrievers, poodles, etc. If it is found that the dog has a tumor, you should take the dog to the pet hospital for medical treatment in time to see whether surgical removal is needed.
