I am looking for information on how to encourage a dog to either lick or get really excited. I have had 2 experiences but have yet to be mounted. Is there a jelly or cream that works well. This is my first post so I dare say you will tell me if I have it wrong.

Well I think you did fine for first post.
And welcome.
That said I am not much help with your question.
I train horses.

Well, in my experience, I've never had to get a dog to lick using food or other things, they just did it all on their own,...

For getting them to mount... if they're kind of reluctant, what I've found is to get really playing with them, like down on the floor, on your hands and knees, and a lot of friendly rough housing and touching, maybe then try and get him to chase you a bit on your hands and knees when he's in the mood and this gets them exicted enough to try and mount usually, then lots of praise and pets... They catch on quick if you keep that up!

If I think of anything more...I'll post again... but praise works wonders when the'yre doing something good.

I have always tried to, and recommend, stay away from food inducements. Either your animal is oral or they are not. Just like with people, some love to give head, some absolutely refuse. Its literally and figuratively a matter of taste.

BUTTER, Butter, butter!! has always worked w/ any dog or bitch

i find that masterbating will to precum tends to be a big insentive OR use a small amount of food to get him and yourself started.
