Pentoxifylline can also be of value in more scarring cases for help with tissue perfusion of systemic antibiotics.įeline acne is a common finding though in many cases does not promote the client to seek veterinary attention. The author has also used tacrolimus in some cases with limited response. Doxycycline has been shown to be effective and whether this is due to antibiotic or other effects is still to be determined.(Bensignor and Guaguere 2004) Rarely topical or systemic glucocorticoids or retinoids may be needed. In severe cases systemic antibiotics are indicated. Recently the author has had success utilizing Douxo ® Seborrhea Spot-on with 1% phytosphingosine as a spot on application twice weekly. Benzoyl peroxide shampoos and gels are often prescribed for milder cases or as adjunctive therapy in more severe cases. Treatment is not always needed in young or mildly affected dogs. Cellulitis with larger plaques may be seen. Lesions include comedones, papules, pustules, nodules and furuncles on the chin, lips and muzzle. Trauma and ingrown impacted hairs may also play a pathologic role in some cases.Īcne is most common in short coated breeds with Boxers, Great Danes and Doberman pinschers being especially prone. Follicular rupture (furunculosis) may also occur and contributes more to the inflammation by inducing a foreign body reaction. We do know in dogs that the abnormal follicles become infected, usually with staphylococcus intermedius. In humans the local fatty acid deficiency then causes the follicular hyperkeratosis.
We do not know if canine acne relates to abnormalities in sebaceous secretions that cause a localized fatty acid deficiency. Some cases do have prominent sebaceous glands in dogs with acne. Work in dogs prone to acne has not been done. It has been suggested that dogs are different because hairless breed comedones have fatty acid profiles suggesting epidermal derivation and not sebaceous. 2005) Not only has little been done to study the disease in cats and dogs compared to humans we do not even no if it is the same in cats and dogs.Ĭanine acne is believed to relate to abnormal follicular keratinization resulting in comedones. In humans acne is a complex disease and there is a role played by hormones, diet, the bacteria Propionibacterium acnes, sebaceous glands, and possible keratinocyte activation.(Heymann 2004 Adebamowo, Spiegelman et al. There is little to no work suggesting canine or feline acne has similarities to human acne. The current discussion will cover acne, nasodigital hyperkeratosis, acne, stud tail, ear margin dermatosis, linear keratosis, schnauzer comedo syndrome and idiopathic facial dermatitisĭogs and cats may both develop a disease referred to as acne. There are a variety of keratinization defects that affect specific body locations, some of which are breed or species specific.
