Frankenstein

This is my new dog Frankenstein. I was curious about basset hound training tips, potty training tips, and information on food intake. I did research before getting him but I think I’ve been giving him too much food because he’s been having a bit of diarrhea plus he threw up last night. He’s only been here for two days so I know part of it is probably due to stress, but I still want to make it as easy as possible for him to ease into life here. I saw online that basset hounds should eat two cups of food per day and was curious if that has been working for you guys and how many treats do you give per day while training? Also, is it recommended you get a slow feeder for them because he eats his food incredibly fast so I’m worried that’s also a factor. I just am a very anxious person especially when it comes to my pet friends! Sorry if it seems like too much and thank you for your time.
