A two-year-old, neutered female Cocker Spaniel presented with a history of several days’ malaise, mild diarrhoea, inappetence and fever (40 C). Before any drugs were administered she then developed multiple widespread skin lesions consisting of sharply-demarcated ulcers up to 3cm diameter with swelling, overlying crust and surrounding erythema. Figures: a) profile of the … Continue reading
There are lots of dogs out there with diffuse or macular erythema, petechiae, ecchymoses and other varieties of ‘red skin’. ‘Flushing’ is a term used to describe erythema in people caused by vasodilation: it is usually transient and benign. Persistent flushing is somewhat more worrying. The present case involves a 9 y.o. FN Labrador with … Continue reading
Amazingly (actually maybe it’s not amazing :/) there appears to be just one published study on ultrasonography of canine anal sacs. This reflects a general lack of enthusiasm for anyone getting to grips with pathological conditions of the AGs. And it’s a sad state of affairs since they’re easy and rewarding to scan. That one … Continue reading
This is a rare but very striking condition. First described in 2002: https://www.ncbi.nlm.nih.gov/pubmed/12358612 Vet Dermatol. 2002 Oct;13(5):275-81. Dermal arteritis of the nasal philtrum in a Giant Schnauzer and three Saint Bernard dogs. Torres SM1, Brien TO, Scott DW. And subsequently reported in a handful of further dogs. St Bernards and GSDs appear particularly over-represented amongst affected dogs. … Continue reading
This case is an illustration of why some deep pyoderma cases in short-haired breeds can be difficult to fix. Obviously it’s sensible to rule out factors such as hypothyroidism, HAC, demodicosis, immunosuppressive drugs etc. This particular patient had been through that process quite thoroughly. After months of struggling, we examined the lesions under … Continue reading
Three forms of Demodex are carried by dogs and are sometimes associated with dermatitis D. canis and D. cornei have been shown to be morphological variants of the same species. Which makes sense since they can often be found in the same skin scrapes from dogs affected with conventional demodicosis. Vet Dermatol. 2012 Dec;23(6):509-e101. doi: … Continue reading
Amongst the various potential adverse effects of cyclosporine in dogs is a gingival hyperplasia. It’s not dramatic in this patient: they can be much worse. The same phenomenon is seen in people. In human medicine it can be managed with azithromycin in capsule or toothpaste formulation. In dogs this approach has proved less successful: Vet … Continue reading
This could be a difficult diagnosis unless, as here, the owners have actually seen the dog chewing buttercups. This poor chap was salivating intensely and had widespread patchy erythema of the oral mucous membranes and ‘geographic’ pale discolouration plus sloughing of the lingual mucosa. He recovered fully within a few days… Continue reading
An 18 month old crossbreed was presented with a two month history of intermittent pyrexia and malaise. Recently he had become polyuric/polydipisc and hypercalcaemia was detected. His ultrasonography is striking: This is an area of retroperitoneal fat: There are numerous small, discrete hyperechoic nodules. And the same is true for his subcutaneous fat this is … Continue reading
Hepatocutaneous syndrome is quite a complex subject -these are just a couple of images from this poor chap with severe footpad fissuring and crusting plus characteristic liver changes on ultrasonography… Continue reading
