Damp eczema and hot spots in dogs
Does your dog love a summer dip in the sea or lake? Do they have a thick, dense coat? If so, they might be more prone to damp eczema during warmer months. Discover how to prevent hot spots and what to do if you suspect your dog has developed them.
What is eczema?
Damp eczema, wet eczema, or "hot spots" all refer to a superficial skin inflammation on your dog’s skin. It’s caused by an overgrowth of your dog’s natural bacteria. The eczema produces a weeping discharge that can crust over, sometimes looking like small sores.
Why does eczema occur?
Bacteria thrive in warm, humid conditions, which is why dogs with thick coats who swim often can develop eczema. It can also occur if your dog frequently gnaws, licks, or scratches their skin or coat for any reason.
What can I do to prevent eczema?
Some dogs are more susceptible to eczema than others, though the exact reason isn't always clear. However, you can take steps to reduce the risk. If your dog enjoys summer swims, try to dry them thoroughly afterwards. Sometimes, the water itself can cause irritation, so rinsing your dog in the shower after a swim can help. For dogs with thick or long coats, clipping or shaving them during summer can also make a difference.
What should I do if I suspect my dog is affected?
Not all cases of damp eczema require a vet visit. Often, you can try treating it at home first.
Follow these steps if you think your dog has wet eczema:
Clip or shave the fur away from the affected areas, right down to the skin. Carefully feel over your dog's entire body for any crusts or eczema. Make sure to create a generous border of healthy skin around each patch, as all affected areas need treatment. Leaving any untreated patches can allow them to spread quickly. It’s better to clip or shave too much rather than too little!
Wash the area with a bactericidal shampoo or mousse containing chlorhexidine. You can find various dog shampoos over the counter at pharmacies or veterinary clinics. Remember to leave shampoos containing chlorhexidine on the skin for at least 10 minutes to ensure they have a germicidal effect. If your dog is impatient, a mousse might be a simpler option as it doesn't need to be rinsed off.
If your dog is scratching or licking the area, you might need to use a cone collar. Licking introduces moisture and bacteria, hindering the eczema’s healing process.
When should I contact a vet?
Contact your vet if your dog seems to be in pain from the eczema or isn’t responding to treatment. If your dog experiences recurring eczema problems, book an appointment too, as there might be an underlying cause, such as allergies.
