This is a common question for many dog guardians- how often should they feed their pets. Experts say that it is recommended to feed your adult dogs twice a day; one in the morning and one in the evening. But puppies below six months of age require thrice or four times a day of feeding or as required by their veterinarians.
Dogs normally get excited on the mere sight (or smell?) of food but newly adopted dogs get a little finicky especially in a new environment. You need to gain their trust first and of course they are still adjusting to the new environment and this is the perfect opportunity to teach them scheduled feeding.
You can start by offering him a bowl of food and getting it after 10 minutes regardless if he has touched his food or not.
At the next scheduled feeding time, put the bowl back down, again for only ten minutes. And in no time your dog will learn that he needs to eat when the food is offered.
With regularly feeding schedule you will be able to establish a routine for your dogs, not only that, you’ll be able to spot easily if your dogs are not feeling well. A sudden change of appetite could be a sign that you need to bring your dog to a veterinarian.
Another benefit of set feedings is that a dog that eats on a schedule poops on a schedule. In addition, if you live in an urban area, leaving a bowl of kibble on the ground all day can attract pests, like ants, cockroaches and mice. It is to everyone’s advantage to keep feeding times regular.
