first steps:: an animal must be fed according to its weight , so take note of this information, available on the internet or on the food packet (little change depending on the sex, sports activity, and if the animal is sterilized.

2! use a scale to weigh the food, separate the quantities in two, 1 half for the morning and one for the evening

note: you can add cod or salmon liver oil to improve the shine of the coat, it also improves the immune system, also let your pet eat a bit of grass, it helps to poop more easily. For your dog you can give them cooked rice ,some green beans or a bit of boiled carrot (not too much ,carrot contain a lot of sugar)

For water ,change water two time per day ,your petz need fresh water especially in summer time!

Hope helping
