For food, I feed my dog ProPlan but there is better out there. I tried experimenting with other cheaper grocery store brands but she ended up putting on alot of weight and alot of waste. I've switch back to Proplan and now she much more energetic, less waste and lost alot of weight. She has to lose another 5lbs or so but its been only a week or more.I would not recommend feeding the bloodhound the same food if its over 2 yrs of age. Different nutritional requirements. Also, limit the amout of food you feed your bloodhound.Overweight can cause hip/joint problems in the future.

As to your retriever, that would be a dog behavioristspecialty.
