How many times a day you feed your pup depends upon his age when you acquire him. Below is my schedule of feeding.
Feed a young pup three to four times daily. A good plan is to feed him when you first get up in the morning. Then leave a small amount of dried food down for the daytime feeding (one meal's worth) if you work. His third feeding comes as soon as you get home from work, with his fourth feeding around 9 or 10 at night. (This gives him enough time to eat his meal and relieve himself before you retire for the night.) All dogs should be fed a dry dog food as the basic food. I use Eukanuba Puppy Food, Small Bites. Any quality name brand puppy food can be used for the first year. Other good ones I have found are Bil Jac, Iams, ANF, Science Diet or Alpo Dry Puppy food. Never use a generic brand of dog food. A good quality dog food is a must! It is much better to invest in a good dog food and feed your dog well, than to spend the money with your veterinarian!
You should get a package of food from the pup's breeder that your pup has been eating. You should feed this for at least four days after you bring him home. If you do decide to change him to another food, then do so in 25% increments over a four day period. First day, add 1/4 new food to 3/4 present food. Second day, 1/2 to 1/2; third day, 3/4 to 1/4, fourth day, all new food.
Feeding times should be done on a 7-day schedule. If you work or are away on weekdays the pup should not be fed during those "away" hours on the weekend.
My adult Corgis generally get two cups of dry food with warm water poured over it one time daily in the morning during the summer months and twice daily in the winter.
Morning Feeding: Feed the amount stated on the package directions. Usually around 1/2 to 3/4 cup in an 8-10 week old puppy. Mix with warm water and add one Tablespoon of a good meat-type canned dog food (I use Kal Kan chopped) and one Tablespoon of plain yogurt. Let mixture sit for 5 minutes at room temperature before feeding. Do this when you first get up, as you will have to give the pup time to eat and relieve himself before you go to work.
Daytime Feeding: leave dry kibble down during the day if you are not going to be there to feed him yourself. Or feed as above, leaving off the yogurt. Leave this feeding off at three months (12 weeks) of age.
Late Afternoon Feeding: feed as for morning feeding, leaving off the yogurt. You may substitute one hard boiled or scrambled egg for the canned meat on occasion. Add heartworm preventative (either one of the daily kind or the once a month wormer - you can also get the once a month heartworm medication with flea control, too which I highly recommend.) Your dog should be kept on heartworm preventative medication for the rest of his life! Check with your veterinarian to determine which medication is best suited to your individual pup. FOLLOW HIS ADVICE!
Late Evening Feeding: This is for 8-9 week old pups. Feed same as late afternoon feeding. Leave this feeding off after 9 weeks.
USE COMMON SENSE! Alter the amount you are feeding your pup if he begins to gain weight. A Corgi should always have a discernable "waist" right behind the ribcage in the loin area. Leave off one of the feedings earlier than called for if you see he is becoming too heavy.
After six months of age, you may wish to feed only one time daily (or if your pup is one that leans to the pudgy side!), but I recommend feeding twice a day to spread the dog's nutrition throughout the day. Just be sure to divide the recommended feeding amount in half.
FEED NO BONES! Bones can cause intestinal impactions. Feed no milk or raw eggs. Your dog cannot digest milk or raw egg whites. You may give your dog 100% rawhide chew bones or Nylabones. They may also safely be given the packaged, natural sterilzed bones available your favorite pet shop. The chew hooves that are so popular can cause slab fractures of the teeth, so feed them with caution or not at all. NEVER let your dog eat grapes or raisins, onions, chocolate, cocoa or macadamia nuts. All of these can be fatal to a dog!
TREATS: I keep a regular supply of Milk Bone dog biscuits (small) on had to use as rewards and treats (and occasionally for a bribe). All the Jimanie Corgis are attuned to the rattle of the biscuit tin or if they hear the word "cookie" they all come running! Give treats no more than a couple of times a day. You don't want "cookie" to become another meal.
