Hello there! I'm glad you're reaching out about your concerns regarding ProHeart 12. It’s completely natural to be attentive to your pet’s well-being, especially after they receive a treatment.
ProHeart 12 is a long-acting injectable heartworm prevention for dogs. While it's generally safe and quite effective, some dogs might experience mild side effects. These can include vomiting, diarrhea, decreased appetite, or lethargy shortly following the injection. Typically, these symptoms are mild and resolve on their own.
To help your pet feel more comfortable at home, make sure they have access to plenty of water and a quiet, cozy place to rest. Light meals may be easier on their stomach if they’re experiencing tummy troubles.
However, be on the lookout for more serious reactions. If you notice your dog has difficulty breathing, facial swelling, severe vomiting or diarrhea, or seems unusually weak or disoriented, these could be signs of an allergic reaction, and you should seek veterinary attention promptly.
If your pet's symptoms persist or if you notice anything unusual that worries you, I recommend booking a video consult with one of our vets at Dial A Vet. We’re here to help and provide guidance specific to your dog’s needs. Stay calm and give your furry friend some extra love and cuddles today!
