Hypoadrenocorticism, also known as Addison’s disease, is a condition in which the adrenal glands do not produce enough glucocorticoids (steroids) to allow normal body function. This condition is considered rare in cats, but numerous cases have been reported. Affected cats often have a history of waxing and waning periods of lethargy, decreased appetite, and weight loss. Long-term, cats with hypoadrenocorticism require medications to supplement the substances released from the adrenal glands.
Lipomas are benign tumors of fat seen in middle-aged to older animals. Sometimes these tumors grow in between muscle layers are called infiltrative lipomas. Lipomas are benign and do not typically behave aggressively. Liposarcomas are the malignant form of the disease. These tumors are usually diagnosed by a fine needle aspiration, though biopsy or advanced diagnostic imaging may be required before surgery. Surgery is the best course of action for pets with lipomas and fat-based tumors.
The adrenal glands are responsible for hormone production. Overproduction of these hormones typically manifests as Cushing’s disease (hyperadrenocorticism). Typically, these tumors are benign in nature and can be treated medically, though malignant tumors (e.g., carcinomas/adenocarcinomas) are possible. In these cases, surgical excision is generally required. The prognosis for patients with adrenal tumors is generally good if surgical removal is complete.
The adrenal medulla is responsible for producing hormones such as epinephrine and norepinephrine. Dysregulated replication of the chromaffin cells of the adrenal medulla lead to development of a pheochromocytoma. These tumors produce excess hormone that leads to episodes of hypertension and tachycardia. Early detection via abdominal ultrasound is imperative for surgical success. CT scan prior to surgery is recommended as these tumors have the potential for vascular invasion leading to post-operative complications. Staging is recommended given that approximately 40% of patients will have evidence of spread at time of diagnosis.
The determination and wiry coat hark back to terrier breeds, with a sprinkle of flat-nosed breeds, giving them their distinct expression. The Affenpinscher originally called the Miniature Pinscher his litter-brother, with both often born in the same litter. These were often scrappy little farm dogs, helping to keep the farmsteads free of rodents.
The Afghan Hound has glamorous good looks that belie his grit and stamina. This ancient breed runs swiftly, is relatively independent and gives affection only to those who have earned it.
Afoxolaner is used to treat and control flea and tick infestations in dogs. Sometimes afoxolaner is used for the treatment of sarcoptic mange or demodectic mange. The tablet should always be given as directed by your veterinarian. The majority of dogs have very few side effects from afoxolaner, provided it is given according to label recommendations and at the prescribed interval. If you suspect an overdose or negative reaction to the medication, call your veterinary office immediately.
Our knowledge of bird nutrition is constantly evolving. This is due both to heightened awareness of the importance of nutrition and to increased research into the needs of different bird species. As with all other animals, birds need a proper balance of carbohydrates, proteins, fat, vitamins, minerals and water. Different species of birds often require different foods.
The African grey parrot, originally from central Africa, is a highly intelligent bird, now commonly bred in captivity as a pet. This elegant medium-sized bird is entirely grey with a strikingly red, short blunt tail.
Aggression may be defined as any threat or harmful behavior directed toward another individual or group. Aggression in dogs commonly includes body language or threat displays such as a hard stare, growling, barking, snarling, lunging, snapping, and/or biting. There are many different categories or types of canine aggression including territorial, possessive, maternal/protective, pain-related, predatory, frustration, social conflict-related, sexual, disease-related, and fear- or anxiety-related aggression. The most common presentation of aggression is fear or anxiety motivated. The treatment of aggression will depend on the cause of aggression. Aggression should first be discussed with your veterinarian regarding the most appropriate treatment.
