Just change the water after you dog has licked it otherwise your betta will be living in water with germs in it! But I don't think it will get sick...I used to have 3 bettas and while I was cleaning out one of their bowls, I was in the middle of taking one out when I accidentally dropped it on the floor! I was so scared and worried it would get sick but it seemed completely fine! And I'm pretty sure floors have way more germs than a dogs tongue!
Also, I'm not sure if you already do this, but there's a solution that you put into the water' after you've changed it, that can help remove different types of stuff that can harm the betta, but I forgot the name of it. I used to get it from my local pet store, so I think yours will probably have it.
There are a lot of wevsites with useful information like www.bettafish.com.
I hope this helped
