Hi Mitch, I am thinking that Bentley may have swallowed something you don't know about. Diarrhea is usually the first sign of an obstruction, then vomiting, and drooling water from the mouth. These symptoms usually happen first, and they can also become lethargic, but not always. They can have these symptoms and still eat, drink, and play like normal. I have a male EB named Dozer and he has a habit of swallowing sweat socks, he has swallowed socks on 4 occasions. Only once did he show any signs of obstruction at all, the other times he didn't show any signs, just developed diarrhea and vomiting, but still ate and drank and played normally. He was able to pass the socks each time by either throwing it up, or by pooping it out. The second time he did this, and became really sick, we took him to the vet and they felt his stomach, and she could feel a mass in there, she did an X-ray which only showed a shadow in the intestine. We didn't know what he had swallowed at that time, but we knew he had swallowed something. She gave him IV fluids, pain medication, and a laxative. She send us home with a high fibre canned food, that we had to feed him a Tbsp. every 1 to 2 hours, to help move his bowels along. That evening he was able to poop out the sock, it was my little grandsons sweat sock. The vet was really surprised he was able to pass the sock without surgery. I would continue to watch Bentley for symptoms, and if he doesn't improve or gets worse I would take him to the vet and do either an X-ray, or a barium X-ray to see if he has an obstruction. He could have swallowed a piece of the crate, or one of his toys or stuffed animals, it doesn't have to a big piece, even a small piece can cause problems. It doesn't have to be an obstruction, but it can cause an irritation in the stomach and cause the same symptoms. We cannot give Dozer or Blossom anything soft, no stuffed animals, no tennis balls, no pillows, no blankets, and especially no rope toys, they eat all of these, we cannot even give them a crate pad, they have to sleep on the plastic tray, because they will eat the pad or pillow. The only toys that we can give them are the hard Kong toys. Please keep us posted on how Bentley is doing, and what the vet says. I hope it's nothing serious and that Bentley is okay. Sending love, hugs, and prayers your way.
