Okay, so over Easter weekend me and Baxter had SO much fun!

My sister and I took him to the new dog park that opened in my hometown, and there were actually SMALL dogs that he could play with! He had so much fun! After that, me and my boyfriend took him on a hike up this mountain that took total about an hour. He walked the WHOLE way!


Of course he was pooped afterwards.
ANYWAYS, once back at home, I noticed he was scratching, and lo and behold, I found a flea on his stomach!



I was horrified and sad! I went to petsmart today, trying to find some advice on what I should use to get rid of the fleas and also to prevent future fleas, and of course, NO ONE would help! I would ask for a suggestion, and the lady would simply say we have this and this. Wouldn't explain anything to me or anything! It was very annoying! I told my boyfriend, who I was with at the time, that I would just post on my website for some advice. He laughed and we left and here I am!
So, any advice on what to use to get rid of his fleas, and also for flea prevention in the future?
Thanks guys, I love y'all!
