that all goes well. Starting Theo's deworming treatments tomorrow. I am going to listen to my vet on this one. I don't feel great about it, but we spoke for over an hour on the phone and this is the next step that needs to be taken. I didn't know that Giardia can stay in a dog for YEARS! I also didn't realize that its hard to get rid of once a dog has it. Symptoms can come and go. He has most of the symptoms but then again he has all the symptoms for IBS as well. He has to take the meds once a day for 5 days. Then in 3 weeks another 5 days and 7 weeks after that another 5 days. What concerns me is if he doesn't have parasites, am I harming his already fragile gut even further? This is what is bothering me. I don't want him to be worse off. Has anyone ever use Fenbendazole before? Would appreciate any rayz you can spare, that all goes well for Theo.
