I have a now 5 month old basset hound. I got her when she was close to 10 weeks old and she arrived to me from he beeeder with multiple intestinal parasites. Giardia, hookworm, and coccidia. We have treated for all of those and it took some time but she seemed to be doing better. Over the last week she has been having off and on again diarrhea. I also noticed her start trembling when she would try to lay down and sleep. She started to growl at me when I would try to pick her up and she was sleeping. I have also noticed she seems itchy a lot of the time and that’s been an ongoing thing. I knew she was in pain and took her to the vet last Saturday. She acts normal, healthy, and happy most of the time. The vet seemed to think she was fine since she was acting normal at the vet and no apparent clinical findings. They did an abdominal X-ray which showed intestinal inflammation and her bowels were full with stool and gas. They gave her an allergy shot for the itching which didn’t really seem to help. Did no other work ups and the vet didn’t think it was necessary and said she probably just got into something she shouldn’t have ate and put her on flagyl. Her last 2 stool samples have been negative for parasites. She is still a week after taking her to the vet not 100% back to normal she had on and off diarrhea during the week and GI upset. She is still trembling occasionally when she lays down. The vets next recommendation is to do another stool sample and GI panel to check for bacteria which is going to cost a pretty penny. I just don’t want to keep dumping my money into stuff that’s not going to find answers and if she doesn’t get better that’s what I will proceed with because I want to do whatever is going to get her better. I don’t know if I should assume she still has an intestinal parasite and just keeps having false negative stool samples or if there is something else going on. Just not sure what to proceed with and what kind of diagnostics she should be doing! Any thoughts help?
