Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
The cause is idiopathic, or unknown. One commonly accepted theory is dyskinesia that originates in the basal ganglia of the brain, which is responsible for motor control. [1] Other possible causes are low glucose and/or calcium levels in the blood, often experienced by lactating dogs.
Sudden acquired retinal degeneration syndrome (SARDS) is a disease in dogs causing sudden blindness. It can occur in any breed, but female dogs may be predisposed. [1] Approximately 4000 cases are seen in the United States annually. [2]
The cause is still unclear. [6] The pathogen that triggers the disease and contributes to its development has not yet been identified. It is presumed to have a multifactorial, heritable, autoimmune etiology. [2] The process is rapidly progressive, culminating in status epilepticus and ending fatally for the dog. [5]
Dogs don’t rely on their eyesight like humans do. Their eyesight isn’t as strong as ours, so their sense of smell in particular tends to be much more important.
Different activities had varying effects on participants’ brain waves. Playing and walking with a dog increased the strength of the alpha-band oscillations, the authors found, which generally ...
Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
Skin conditions in dogs are very common, so it's important to recognize the symptoms and understand the factors that cause them. Dr. Rebecca MacMillan, a vet with over 15 years of experience, says ...
