New canine dermatology findings promise relief for itchy dogs
Flea allergies: when small pests pose a major threat
While fleas can be an inconvenience for most dogs, they’re much more than that for canines with a flea allergy. When fleas feed on your dog, they inject a small amount of saliva into the skin, and the antigens or proteins in their saliva may cause a reaction in dogs that have developed a hypersensitivity to it14. In turn, your dog becomes itchy and uncomfortable, spending more time chewing, biting, and scratching than fetching or interacting with others.
Flea Allergy Dermatitis (or what most people simply refer to as “flea hypersensitivity”) is the most common dermatologic disease among domestic dogs in the United States15, and a recent health report showed a 12.5 percent increase of the disease in dogs over the last ten years16. How can we explain such a significant increase? For one, climate change. NASA recently showed that 2020 was the warmest year on record17 and warmer average temperatures mean shorter and milder winters and hotter, more humid summers, creating the ideal conditions for fleas and ticks18. Another explanation is indoor heating: fleas used to become less active in winter, but now our warm, comfortable homes provide an environment in which they can thrive.
As flea season becomes a year round concern, veterinarians have begun recommending that pet owners provide their dogs with flea treatments 12 months of the year. Surprisingly, veterinarians biggest challenge is not managing the pests themselves, but rather getting pet owners compliant (that means a pet owners ability to administer a treatment according to the veterinary recommendation) with parasite treatment usage. As a result, a significant amount of research and development has gone into creating flea treatment options that are both effective and easy to use for pet owners, ranging in formats from pipettes, collars, injections, and tablets19. Some researchers are even exploring longer-acting dosing options so that pet owners can treat their dogs several times a year rather than every month20.
Pyoderma: the not-so-friendly bacteria that’s more and more difficult to treat
Pyoderma is another one of the most common disorders in canine dermatology. Superficial pyoderma is a bacterial skin infection that covers dogs with lesions and/or pustules that are red and sore, alongside scaling, crusts, and collarettes (a round lesion with a scaly, peeling edge), while deep pyoderma affects the deeper layers of the skin. In both cases, the primary bacteria is staphylococcus pseudintermedius21 (or staph).
Pyoderma may not be a new disease, however veterinarians report it has become more difficult to treat with the increasing prevalence of staphylococcal antimicrobial resistance22. Yes, just like humans, an increasing number of dogs are developing antimicrobial resistance23, which is what happens when harmful bacteria develop the ability to resist the antimicrobial (antibiotic) drugs that are designed to kill them24.
While this doesn’t make it impossible to treat your dog, it does make it more complicated, and veterinarians have had to get creative when managing the disease. For example, a recent study performed in Mexico studied the effects of using textile bodysuits containing zinc and copper (which have shown antimicrobial activity) in dogs with superficial pyoderma and the results showed a steady decrease in cocci and yeast bacteria over 15 days25. Meanwhile another study explored the effectiveness of fluorescent blue light therapy on dogs with deep pyoderma, which showed it very well could be a useful tool in managing pyoderma when used as a supplemental therapy26.
Your dog’s future: diagnosis and treatment are the keys to wellbeing
Remember: veterinary dermatology is a complex field, with a wide variety of skin disorders sharing the same symptoms, so it’s important to consult your veterinarian about your dog’s skin concerns so they can run the appropriate testing, provide a diagnosis and implement an adapted treatment. If you have any concerns or questions about your dog’s diagnosis or the management of their treatment, speak to your veterinarian about the different options available and let them help you identify suitable solutions for you and your dog.
