One of the things we have to learn when adopting a Greyhound is that nothing on the counter is off limits, in their mind.  All food they have smelled before has been theirs.  Not only that, but dogs are opportunistic scavengers from way back. Your dog is rewarded every time he jumps on the counter and finds food or something to chew, so it is very important to stop counter surfing ASAP, preferably before it starts. This behavior is not only irritating but it can be dangerous. Hot food can burn, glass can break and cause cuts, or your dog could ingest something that is harmful to them. Counter surfing should be curbed as soon as possible to avoid a vet visit. There are many strategies we can undertake to prevent it though.
