Oh Karen, poor Dusky. What a run around with the vet...vets! Can't understand how they're unable to see on the x-ray what's causing the blockage, at least some idea of what it is, if it is something that can be passed. My Lab Jingles had a similar bout, vomiting and diarrhea. The vet showed me the x-ray and declared, "multiple foreign objects!" He could see a bird's skull, "gravel" and sand, small stick pieces. Luckily she didn't require surgery. Do you have any idea what Dusky may have gotten into, eaten? Is he a sock eater? Socks are the cause of many a blockage. Breaks my heart, no vet willing to do the surgery under a payment plan. Hoping and praying Dusky is doing better... Please give him a hug and kiss for me.
