dogs poop a lot and they fart a lot, so dont feed dogs a lot of beans cuz they tend to get a tad gassy
Your vet will tell you, but need varies with size and age.
yes
No it wouldn't but make sure it's low
No. Intake balanced with needs means to me that you are putting into your body the same amount of energy that you burn each day. There would be no storing of fat and no burning of fat. If you were exercising and gaining muscle you would actually gain weight. The only way I could see weight loss occurring while caloric needs were balanced with caloric intake would be if you became less active and had muscle atrophy while simultaneously realizing your reduced needs, thus reducing caloric intake accordingly. You would lose the muscle weight.
gender, age, and health
An individual can estimate his or her caloric needs for the day by amount of energy that they require to use. This will also be influenced by the macronutrients that are required per given day. Generally, males need more calories in a day than females.
in the UK NO the dog is chosen for you on your needs and the dogs needs
It depends on your individual caloric needs, but I think it's about 50 grams.
3500 calories, fool. Obviously this is the caloric intake above your baseline needs.
The UK Department of Health recommends 1845 calories for girls aged 11-14 and 2110 calories for girls aged 15-18. Athletes may need significantly higher caloric intake.
By 18 months most dogs should be on adult food. However, a working dog may have higher caloric needs, so consult with the dogs' vet to make sure your dog is getting the right quantity of an appropriate food.
Personally, I would choose Purina's Beneful for Small Dogs. I think it has all the vitamins and nutrients a small dog needs to grow and stay healthy. If its a puppy, get the Beneful for Puppies.
Gain weight.
