As far as how much to a feed a dog, it is recommend to follow the instructions provided on the particular brand of dog food purchased. Most of the charts will determine the number of cups a day the dog should eat based on its age and weight. Take the total number of cups recommend and divide that by the number of meals the dog is being fed. Of course, that recommended amount can be adjusted slightly based on the dogs individual needs. For example, dogs that spend most of the day outdoors tend to need more food during the winter to maintain their ideal weight since they are burning more energy just to maintain their body heat in the cold.
During the dog’s schedule meal time, give them 3-4 minutes to eat its food. If the dog begins to lose interest and focus, take the food away after the three minutes is up and do not feed the dog until the next scheduled meal time. A dog in the wild quickly learns that food is a precious commodity. When a dog in the wild loses interest, the other dogs in the pack do not save parts of their kill for that dog to eat at a later time. The dogs will stay focused on eating because they don’t know when their next meal is going to be. This develops what is referred to as “food drive”. The same type of drive can be established in the domesticated dog through scheduled feedings.
Free feeding (keeping the your dog’s bowl filled with food and letting it eat whenever it wants to, in whatever volume) seems easy and convenient to many owners, however, p lacing your dog on a feeding schedule has numerous benefits over free feeding.
