Dogs and cats of any age may be affected, but dogs are far more likely to suffer from anal sacculitis than cats. Dogs and cats with anal glands that do not express naturally may exhibit specific signs, such as scooting the backside upon the ground, straining to defecate, and excessive licking of the anus.
An anal sac adenocarcinoma is an uncommon and aggressive malignant tumor found in dogs that arises from the apocrine glandular tissue of anal sac. The disease exists in cats as well, but is much less common in that species. [1] They are the second most common cancerous cause of hypercalcaemia (high serum calcium) in dogs, following T-cell ...
The pituitary gland produces a hormone that signals the adrenal gland to produce cortisol; a tumor can cause it to produce the adrenal-stimulating hormone even when it is not needed. [ 117 ] [ 118 ] Signs include increased appetite, increased drinking and urination, a pot-bellied appearance, muscle weakness, and lethargy. [ 117 ]
SSC in the anal canal most commonly causes bleeding, but may also cause anal pain, a lump, pruritus ani, discharge, tenesmus, change in bowel habits and fecal incontinence. Because these symptoms are so unspecific, and because symptoms of anal carcinoma may not always be typical, this can lead to delays in diagnosis.
A perianal gland tumor is a type of tumor found near the anus in dogs that arises from specialized glandular tissue found in the perineum. [1] It is also known as a hepatoid tumor because of the similarity in cell shape to hepatocytes (liver cells). It is most commonly seen in intact dogs and is the third most common tumor type in intact male ...
Some owners do this routinely if they have a dog susceptible to ear infections or if they have a breed with heavy, floppy ears, which can hide early signs of inflammation. Dogs, like all Carnivorans, also possess two anal sacs, or scent glands. These sacs communicate with the surface of the skin by ducts which open on either side of the anus.
Perianal cellulitis, also known as perianitis or perianal streptococcal dermatitis, is a bacterial infection affecting the lower layers of the skin around the anus. [1] [2] [3] It presents as bright redness in the skin and can be accompanied by pain, difficulty defecating, itching, and bleeding.
Aside from these blisters, the dog may be mostly asymptomatic before the disease progresses further. [4] The blisters are easily ruptured and become painful upon doing so, [4] which can cause the dog to have difficulty eating. [15] As the disease progresses, the infected dog can become severely infirm, and may succumb to further infection. [4]
