Beginning Of Pregnancy in Dogs

  • As we mentioned previously, your dog will be pregnant for around 63 days in total, though this can depend on the breed size. 
  • During the beginning 4 to 5 weeks of the pregnancy, it’s only necessary to be giving your dog the food that they usually eat.
  • This food should be full of the nutrients that an adult dog should be eating, so it should be a mixture of carbohydrates, proteins, fats, vitamins, and minerals.
  • Look for a dog food that has the right balance of all of these. In wet food, the dog food should consist of 5.5-8% protein and 3-5% fat. 
  • For dry food, it should be 22-30% protein and 10-16% fat. 
  • You should already know how much your dog should be eating on a regular basis, but if you are confused at all then speak to your vet or have a look at the references on the dog food that you have bought. 
  • Earlier on, we also mentioned that your dog’s appetite changes during pregnancy. 
  • Well, this doesn’t only apply to what your dog eats. 
  • When your dog is pregnant, they are more likely to drink more water.
  • For this reason, you should make sure that your dog has plenty of water available to them so that they can stay hydrated throughout the day.


Last Week Care in Dog Pregnancy

  • When it comes to the last couple of weeks before your dog is ready to give birth, you will need to change the diet a little.
  • Ideally, your dog needs to be getting around 30-50% more calories than what she had previously, though this depends on the number of puppies that your dog is going to be birthing.
  • If you are confused in any way, speak to your vet for guidance.
  • During this time period, your dog is going to have a 15-30% increase in weight – this is perfectly normal and nothing to be alarmed about.
  • It’s mainly because the body weight is increased from the weight of the puppies.
  • The chances are that you’re not going to need to give your dog any additional supplements during their pregnancy so long as the food that you are giving them is of high quality.
  • It’s worth looking for foods that are fortified with fatty acids too, known as EPA and DHA. 
  • Try to find foods that have fish oil in the ingredients list as this will help you to ensure that your dog is getting enough fatty acids in their diet.
