I saw this on the news.. kinda amazing its just so sad that is a disorder…

This is a whippet that suffers from a condition where myostatin is not produced properly in its body. It is common in the Belgion Blue cow breed as well.

Myostatin inhibiters are currently being tested at John Hopkins to help people with MS/MD and other deseases that effect the muscles.

Myostatin inhibits muscle fat growth. Without it, muscles get huge and fat goes away.

The downside? Tendons and ligaments do not keep up and muscle tears, tendon/ligament strain is very possible.

that dog look scared

i think this is a real dog…….mabey from ichael vick proprety

Since this is probably the only thread of the thousands of them without someone saying this, I’ll say it.

This is a proven fake…

Your default position on ANYTHING should be skeptic. Did you not wonder why there’s not another picture of him anywhere on the internet? Or that the book of world records doesn’t list him? Or anything?

Doubt is the only safeguard against stupidity.

hey,this is absoultly not a real dog.

Double muscling is a trait previously described in several mammalian species including cattle and sheep and is caused by mutations in the myostatin (MSTN) gene (previously referred to as GDF8). Here we describe a new mutation in MSTN found in the whippet dog breed that results in a double-muscled phenotype known as the “bully” whippet. Individuals with this phenotype carry two copies of a two-base-pair deletion in the third exon of MSTN leading to a premature stop codon at amino acid 313. Individuals carrying only one copy of the mutation are, on average, more muscular than wild-type individuals (p = 7.43 × 10?6; Kruskal-Wallis Test) and are significantly faster than individuals carrying the wild-type genotype in competitive racing events (Kendall’s nonparametric measure, ? = 0.3619; p ? 0.00028). These results highlight the utility of performance-enhancing polymorphisms, marking the first time a mutation in MSTN has been quantitatively linked to increased athletic performance.

The wide variety of behaviors and morphological types exhibited among dog breeds and the overall low genetic diversity within each breed make the dog an excellent genetic system for mapping traits of interest. Recently, owners of whippets, an established racing-dog breed, have reported a phenotype of heavy muscling occurring within the breed (http://www.k9community.co.uk/forums).
