no.theres a concrete ramp running into the sea to walk the dog along in the water.theres a few million pound worth of racehorses walked in the same water everyday so it should be sound,ive always used salt water
I'll bet those race horses don't have open sores.Keep the dog out of the sea.
When the wound is completely healed by all means swim it.
The injury is a result of an under-estimated wound allowed to get out of hand, but can be cured by common sense.
Your right there Neil and I would never go to that vet again
