As the dog ages, nerve cells die, and cerebrospinal fluid fills the empty space left by the dead nerve cells. [2] Canine cognitive dysfunction takes effect in older dogs, mostly after 10 years of age. Although there is no known cause of CCD, genetic factors have been shown to contribute to the occurrence of this disease. [3]
A chromosome has been located in dogs that confers a high risk of susceptibility to OCD. [21] Canine chromosome 7 has been found to be most significantly associated with obsessive compulsive disorder in dogs, or more specifically, canine compulsive disorder (CCD). This breakthrough helped further relate OCD in humans to CCD in canines.

[20] Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10% ...
Chromosome 7 is one of the 23 pairs of chromosomes in humans, who normally have two copies of this chromosome. Chromosome 7 spans about 160 million [ 4 ] base pairs (the building material of DNA ) and represents between 5 and 5.5 percent of the total DNA in cells .
As other retinal disorders, PRA can be divided into either dysplastic disease, where the cells develop abnormally, and degenerative, where the cells develop normally but then degenerate during the dog's lifetime. [3] Generalized PRA is the most common type and causes atrophy of all the neural retinal structures.
A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
Vets are looking into a mystery dog illness in 2023, which may be a virus. It's going around the U.S. and can be fatal. What to know about symptoms, prevention.
Chiari-like malformation (CM) the most common cause of foramen magnum obstruction and syringomyelia in dogs. Syringomyelia (SM) is a disease of the spinal cord typified by fluid filled cavities, or syrinxes, within the spinal cord substance but it can cause pain by disrupting the cerebrospinal fluid (CSF), in the brain [1] CM is a condition characterized by the mismatch of size between the ...
