Dog is vomiting, diarrhoeaing, lethargic and has lost a lot (30%) of his body weight over 3 months

I'm so sorry to hear that your dog isn't feeling well. Let's try to get to the bottom of what's happening. Vomiting, diarrhea, lethargy, and significant weight loss are concerning and can stem from various issues, including infections, gastrointestinal disorders, parasites, food intolerances, or even more serious conditions like liver or kidney disease, diabetes, or cancer. Your dog’s symptoms indicate a need for prompt attention.

At home, ensure your dog has access to fresh water to prevent dehydration, especially if they're vomiting or having diarrhea. You might also consider offering small amounts of a bland diet, like boiled chicken and rice, but remember this is only a temporary solution.

Watch for signs such as blood in the vomit or stool, ongoing vomiting or diarrhea for more than 24 hours, extreme lethargy, or difficulty breathing, as these indicate a need for immediate veterinary care.

These symptoms warrant a thorough examination to determine the cause and ensure your dog receives proper treatment. I recommend booking a video consult with one of our vets at Dial A Vet, where we can discuss your dog’s symptoms in more detail and help you decide on the best next steps. We're here to support you and your furry friend through this.
