Misdiagnosed dog

Yesterday my dog had a very hard stomach and he was shaking and few hours later I got home and he was crying so much when I touch his stomach. Went to TAH BELLVILLE and the vet said he just had a sore neck. Which made absolute no sense as he showed no signs of pain the whole day. She gave him to injections and when we got home my dog was breathing so SO fast he looked so I'll, he didn't even looked this bad going in ! We researched this petcam drug and it's ********** side effects and over dosing can lead to death. Later that night, worried sick about him. We heard his stomach making gives growling signs, we treated him at home with our meds, today his up and running and he has some blood in his poo and his poo is very soft and slimy. Now you wanna tell me his neck is sore. 1100 later and my dog isn't right because he was misdiagnosed. And the vet wanted to keep him over in crate lock, do Xray and sedation. Seems like a big money ****?!! I want my dog diagnosed properly WITHOUT paying a cent for another check. If anything happens to my dog, its on TAH BELLVILLE.
