Feeding your pregnant dog

During pregnancy your dog should be fed a high quality, complete and balanced canine diet. You shouldn’t aim to over feed her, so that she rapidly gains weight, as in the first few weeks she still has the same nutritional requirements as a young adult dog.

However, in the final trimester (from around day 40) the puppies start to grow rapidly and put a lot of extra nutritional demand on the mum to be.

This is when she should be transitioned onto a high quality puppy food, as its easier to digest but full of energy and nutrients.

During this time, she may need 30-60% more energy than normal, depending on her breed and the size of her litter.

Are there any risks with prenatal supplements?

Not all pregnant dogs will need a dietary vitamin supplement. If you are feeding your pregnant dog a premium complete dog food, then she is probably getting all her vitamin, mineral and nutrient requirements already.

However, if you chose to give your pregnant pooch a prenatal supplement then you should always take care that the supplement you are giving is suitable and safe during pregnancy!

It’s a good idea to have a chat with your veterinarian first, before you decide which supplement is best for your pregnant dog.

Over supplementing some vitamins and minerals might cause your pregnant dog more harm than good! Let’s take a look at some of the main risks in a little more detail:

Adding lots of calcium into the diet is not advised

Your pregnant dog’s calcium requirements do increase, however, her needs should be met by the increased amount of food she is eating. Calcium supplementation is contraindicated.

If you supplement too much calcium into your pregnant dog’s diet, then you suppress the parathyroid hormone production, and suppress your dog’s ability to regulate her own calcium levels.

Then at whelping or during lactation, her calcium regulation has become lazy as it has depended on the supplements, and suddenly she can’t regulate her own calcium levels.

This can put her at high risk of developing eclampsia or milk fever, a life threatening condition caused by a dramatic drop in blood calcium levels. 

Too much vitamin A and D is not good

Excessive levels of vitamin A in a pregnant dog’s diet has been associated with congenital defects, including cleft palates.

Excessive levels of vitamin D may reduce a pregnant dog’s ability to regulate and use calcium, putting her at higher risk of eclampsia or milk fever.

Therefore, care should be taken when supplementing these vitamins in your pregnant dog’s diet.


Keeping your pregnant dog happy and healthy is the best way to give her new pups the best start in life.

It's important to feed your dog a high quality, complete and balanced diet during pregnancy so that she has all the essential nutrients she requires. Giving your dog a prenatal vitamin supplement might help to give her a little extra boost, and support the healthy development of the pups.

However, over-supplementing some vitamins and minerals such as calcium, vitamin A and D, might put your dog at risk of some health problems. Therefore, it’s important to talk to your veterinarian to check a prenatal vitamin supplement is suitable for your dog.
