1 year old beagle- first time dog mom

I am a first time dog mom and I found myself coming back to this website time and time again when having questions about my pup and his health. I figure it will be more helpful if I allow myself to ask my specific questions! He is a 1 year old beagle (as of July 2018) and has and extremely sensitive stomach. I worry about this dogs health more than my own lol so I hope this forum will be a helpful place to get advice from experienced dog owners and keep my little bear happy and healthy
