US dog sounds likes a 'drowning horse' as he sleeps

This Staffordshire bull terrier sounds like a "drowning horse" when it starts to snore.

Filmed on August 14, Alta the seven-year-old staffy repeatedly makes an unusual noise as they take a nap in their Sheridan, Colorado home.

Alta's owner Candice told Newsflare: "This is my seven-year-old rescue staffy. When he sleeps he makes this sounds like he’s a drowning horse and it causes all the giggles."
