Causes of Dog Interdigital Dermatitis: Understanding th

Section 1: What Causes Interdigital Dermatitis in Dogs?

Interdigital dermatitis in dogs is primarily caused by bacterial infections, such as Staphylococcus aureus and Streptococcus, or by external parasites like mange mites and demodex mites, as well as various fungi. Clinically, this condition is often seen in dogs with damp paws, such as those who are not properly dried after a bath, or those who return from a rainy walk without immediate cleaning and drying. Additionally, living in a dark and damp environment can increase the likelihood of a dog developing interdigital dermatitis.

Moreover, if a dog's immune system is weak, even minor wounds on the paw can lead to interdigital dermatitis. For instance, dogs often encounter sharp objects while out and about, and since they don't wear shoes like humans, injuries are common. However, if the owner fails to notice and disinfect these wounds promptly, they can become infected by pusproducing bacteria, triggering interdigital dermatitis.

Section 2: Symptoms of Interdigital Dermatitis in Dogs

The initial symptoms of interdigital dermatitis are often small blisters similar in size to acne, which may not cause significant pain and are often unnoticed by owners. As the blisters grow, they may contain pus or puscontaining blood, leading to more pronounced pain and symptoms like reluctance to walk or limping. If left untreated, the blisters can rupture, releasing pus, and lead to secondary infections, worsening the condition. In some cases, interdigital dermatitis may not produce much pus, and the blisters contain a lot of blood. After bursting, the affected area may peel, become red, and bleed.

1. Dogs with excessive hair between their toes, which is not regularly trimmed.

2. Shorthaired dogs, such as Bulldogs, SharPei, and Pug dogs, are more susceptible than longhaired dogs.

3. Dogs living in a moist environment and those who enjoy playing in water.

4. Dogs who do not clean and dry their paws after returning from outside.

5. Dogs who frequently injure their paw pads while playing outside.

Section 4: How to Treat Interdigital Dermatitis in Dogs

For minor blisters, washing the dog's paws with warm water or a dogspecific cleaning solution and thoroughly drying them can help alleviate symptoms. Keeping the paw dry is key. If the number of blisters increases, using PovidoneIodine solution for disinfection and promoting skin recovery is recommended. If the dog's paw is swollen with large blood blisters or pus blisters, apply an ice pack to the paw first, remove the surrounding hair, and gently disinfect the area with a tweezer. Then, carefully peel back the most severe swelling to check for foreign objects. Drain the pus and blood from the blisters, apply a hemostatic and woundhealing ointment like "Chuangli De" (Puan特), and wrap the paw. Spray the affected area with PovidoneIodine solution 35 times a day for antibacterial and antiseptic purposes to prevent infection. If the dog's condition does not improve or if the pain is severe, it's essential to seek veterinary care promptly.
