LMAO, I was watching a Dogtona video from last year of the "leave it" competition- the judges put a plate of hot dogs in front of the contestants and slowly moved them forward while the owners (without touching the dogs) had to say "LEAVE IT...". This greyhound left his own plate alone, but ate the hotdogs off the plate of his neighbor and then looked back at his laughing mom like "what?! You said leave my plate alone...and I did!". It was pretty funny.That is so hilarious - dogs aren't stupid, they trust you mean what you say, and if you say "leave it" for one thing, you don't necessarily mean it for ALL things that are exactly the same.
Like the old Jack Russell someone dumped off at our house - we had to teach him not to pee on all FOUR chair legs (for every chair), all corners of the couch etc. one at a time. It just cracked me up.
This link...I love the OP's post, but the comments are dumb LOL.
Today I passed a new place called Indiana Veterinary Alternatives...I looked her up on FB (it's new enough she only has a Facebook, no actual website) and there were links about vegan diets for dogs? I was confused, LOL.
