A roached back can be a sign of subluxation in the dogs spine, as well as disc and or abdominal distress. Have ur Vet check ur dog for abdominal distress as well as your animal chiropractor for spinal related issues.
A roached back looks like an arch in your dog's back. The name roach back was used since the shape looks like the back of a roach, so ur vet will use this term.
