Cytology of lymphoma in a dog. Biopsy of affected lymph nodes or organs confirms the diagnosis, although a needle aspiration of an affected lymph node can increase suspicion of the disease. X-rays, ultrasound and bone marrow biopsy reveal other locations of the cancer. There are now a range of blood tests that can be utilised to aid in the ...
Juvenile cellulitis, also known as puppy strangles or juvenile pyoderma, is an uncommon disease of dogs. [1] Symptoms include dermatitis, lethargy, depression and lameness. When puppies are first presented with what appears to be staphylococcal pyoderma, juvenile cellulitis, a relatively rare condition, may not be considered. [2]
It occurs primarily in dogs and horses, but can also affect humans. In dogs it affects the gastrointestinal system and lymph nodes, and rarely the skin. [24] Mucormycosis is a collection of fungal and mold diseases in dogs including pythiosis, zygomycosis, and lagenidiosis that affect the gastrointestinal tract and skin. [6]
It is usually painful, and there are not lymph node changes, so it does not fit perfectly, but it is possible that there are several things going on (like a tick-borne infection).
Although HS complex is not limited to just these breeds and can occur sporadically in any breed. Primary lesions of HS occur in spleen, lymph node, lung, bone marrow, skin and subcutis especially of extremities. Secondary sites are widespread, but consistently include liver and lung (with splenic primary), and hilar lymph node (with lung primary).
A dog with skin irritation and hair loss on its leg caused by demodectic mange. Infectious skin diseases of dogs include contagious and non-contagious infections or infestations. Contagious infections include parasitic, bacterial, fungal and viral skin diseases. One of the most common contagious parasitic skin diseases is Sarcoptic mange (scabies).
Dogs and foxes are the reservoir for Toxocara canis, but puppies and cubs pose the greatest risk of spreading the infection to humans. [5] Infection in most adult dogs is characterized by encysted second stage larvae. However, these larvae can become reactivated in pregnant females and cross the placental barrier to infect the pups.
The infection can spread through the blood or lymphatic system, causing abscesses to form in other lymph nodes or internal organs throughout the body. Most commonly affected organs are the liver, lungs, kidneys and lymph nodes associated these organs. Abscesses grow gradually over time, and if they are located close to the skin, rupture is common.
