We have a Golden Retriever. Those of you who have one or ever met one know that these are loving, happy, trusting dogs.
A few months ago we noticed that our dog was no longer a TDH fan. The Boy would drop food on the floor, TDH would point it out and the dog would go nowhere near it if TDH stayed there.
The dog came to us about five years ago house trained and had only one accident in the house when we very first got him. Nothing ever since. When The Boy and I went away while TDH stayed home to pack and leave our home the dog #2'ed on the floor not once, but twice.
