Welcome! I am glad you found this site, its full of information and has helped me find out much needed info about our little furbutts! Arent they just great!
Potty training Bobby took awhile. Praising is good when he goes potty on the pad. use a code word, ours is Potty. so when Bobby would go on the pad, I would say good boy good potty and gave him a treat. He eventually got it

he misses the pad sometimes still, he is 1 1/2 years, but he tries to make it. Can't get mad at that
I bathe Bobby every week. For flea control I use Frontline. Its water proof. You just cant bathe them for 24 to 48 hours after applying.
Good luck and can we see some pics of your little guy?
