Swelling, erythema ulceration and crusting caused by the bacteria Treponema cuniculi. Simlar lesions are seen around the vent. Despite its name, it is not always spread by sexual contact and the disease is not transmissible to humans.
Lesions almost cleared up in 10 days after treatment with penicillin injection.
High power view of Sarcoptes scabiei adult mite from skin scraping. This is a very difficult mite to find. Often a therapeutic trial has to undertaken to rule it out, or a blood test performed if the infestation has been present for more than 4 weeks.
An even rarer finding on a skin scraping- a clump of sarcoptes scabiei eggs.
The Dermvet Skin and Ear Clinic is run by veterinary surgeon and dermatologist David Bentley BVSc Cert.SAD MRCVS, based at the Leicester Forest East branch of Bell Brown and Bentley Veterinary Surgeons.
I qualified as vet in 1982 with a BVSc from Liverpool University and have been working in 100% companion animal practice since that time. I enrolled for the Royal College of Veterinary Surgeon’s Certificate in Small Animal Dermatology in 1990 and after 4 years of intensive study both at home and under the guidance of a RCVS recognised specialist in Dermatology, gained my Cert.SAD in September 1994. This involved presenting a casebook of 15 dermatological cases fully referenced and suitable for publication in a professional journal and sitting written, practical and oral examinations.
Since then I have been seeing both first and second opinion/referral skin cases in addition to my general small animal work which I share with my colleagues. I am a member of both the British Veterinary Dermatology Study Group and the European Society of Veterinary Dermatology and to keep up to date I regularly attend courses and conferences relating to dermatology both in the UK and abroad and am a member of a worldwide internet veterinary dermatology discussion group. In the time since I qualified in dermatology there have already been major advancements in the understanding and treatment of small animal skin and ear disease, so it is important that I keep up to date by these methods.
As a result of my interest in ear disease which comes under the discipline of dermatology, I have taken an active interest in ear surgery, attended ear surgery courses and workshops and offer Total Ear Canal Ablation (TECA) and Bulla osteotomy for the surgical management of end stage ear disease. Thankfully, after purchase of a Storz Video Otoscope, the number of cases requiring this surgery in my practice has reduced, but it is still a very useful procedure which can transform a dog’s life when it is suffering with end-stage intractable otitis. The skills that I have acquired allow me to offer a truly complete service for the treatment of companion animal ear disease.

Hair loss around face in 7 month old terrier cross. Juveneile onset demodicosis can be either localised or generalized. Localised cases can self cure. Generalized cases need treating. This case was generalised. as it affected not only the head, but the feet and limbs. This disease is caused by the mite Demodex canis. All dogs are infected at birth from the mother, but the mite is held in check by the immune system.
Deep skin scrapings from the affected skin reveals demodex canis adult mites, nymphs and egg.

When not dealing with itchy , scabby dogs and cats, I like to keep fit and unwind by cycling. This picture was taken on Blakey Bank during the Ryedale Rumble cyclosportive in North Yorkshire.
