A dog that is either lazy, injured, crippled, or dead. This comes from the fact that dog sleds are a well-known form of transportation in Alaska and that if anything bad were to happen to any one of the sled dogs, well, you know, the sled would falter like a car with a flat tire.
"Fuck, my dog's leg just broke! I've got an Alaskan flat tire here and I need to rush him to the vet fast!"
OR
"Hey asshole, keep your fucking pooch away from my garden, or else I'll get my shotgun and turn him into an Alaskan flat tire!"
