Causes of Nausea in Dogs

Nausea in dogs occurs for a variety of reasons. Nausea is also one of the most common ailments among dogs. Regardless of what may be making your dog sick, it is a good idea to take your dog to the veterinarian to rule out any serious illnesses.

  1. Pregnancy

    • Pregnancy can cause your dog's nausea.

      Female dogs that become pregnant can experience nausea, just as humans do. Your dog may begin to vomit within the first few weeks of pregnancy. According to Vet Info, if your dog is experiencing nausea, her appetite may suffer as well. She may not eat heartily until she gets over her period of nausea.

    Intestinal Blockage

    • Swallowing chew toys can cause serious complications.

      If your dog is prone to tearing up her favorite chew toys, then she can also be subjected to intestinal blockage. As a result, your dog may become sick and not feel like herself. An intestinal blockage can be serious; a blockage can lead to intestinal strangulation and ultimately death.

    Hemorrhagic Gastroenteritis

    • HGE can be fatal in dogs.

      HGE is a disease that causes diarrhea (sometimes bloody) and an increase in red blood cells. Your dog can quickly become sick with this disease. Nausea and vomiting will occur with this disease, as well as depression and dehydration. Without treatment, HGE can be fatal.

    Worms

    • Worms can cause multiple problems for your dog if she has an infestation. While it's common for dogs to become infected with worms, serious infestations can spell trouble for your dog. Nausea, vomiting and bad breath can be the initial signs that your dog is infected with worms.
