I have 2 Portuguese Water dogs, a 12 yr. old male and 4 yr. old female. Both were just diagnosed with HGE. Came on suddenly with vomiting, every 2 hours. Couldn’t get in to the vet til 5pm the next day. Never saw signs of bloody diarrhea but noticed a pink tinge in the vomit after 4 hours. Bloody diarrhea was evidenced by vet. Male had to spend night with IV fluids, antibiotics and anti nausea. He was totally lethargic. Female got anti nausea, antibiotics and subcutaneous fluids. She was able to come home with us. Never had HGE before in any pet (and I’ve had dogs for 50 years.) Curious that both should succumb within hours of each other. They both eat dry food with fat content of no more than 9% to 12%. Nothing’s changed in their diets. They aren’t allowed off leash to eat random things. Where did it come from? How did they get it? What are the chances they will get it again?
