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).
A random-bred dog (also known as a mongrel or a mutt) has an average life expectancy of 13.2 [citation needed] years in the Western world. Some attempts [9] [10] have been made to determine the causes for breed variation in life expectancy.
In a very few breeds, such as the American Staffordshire Terrier, Old English Sheepdog, Brittany Spaniel, and Gordon Setter, symptoms do not appear until adulthood or even middle age. [13] In dogs, cerebellar abiotrophy is also usually an autosomal recessive gene, but in a few breeds, such as the English Pointer, the gene is sex-linked.

p53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates , where they prevent cancer formation. [ 5 ]
P53 function can also be responsible for a limited life span where mutations of the p53 gene causes expression of dominant-negative forms producing long lived animals. For example in an experiment using C. elegans , the increased life span of p53 mutants was found to depend on increased autophagy. [ 19 ]
Li–Fraumeni syndrome is characterized by early onset of cancer, a wide variety of types of cancers, and development of multiple cancers throughout one's life. [8] LFS: Mutations in TP53. TP53 is a tumor suppressor gene on chromosome 17 that normally assists in the control of cell division and growth through action on the normal cell cycle.
Dogs can develop a variety of cancers and most are very similar to those found in humans. Dogs can develop carcinomas of epithelial cells and organs, sarcomas of connective tissues and bones, and lymphomas or leukemias of the circulatory system. Selective breeding of dogs has led certain pure-bred breeds to be at high-risk for specific kinds of ...
