My 13 year old Westie, Duke was just diagnosed with TCC last week. Our vet listened to our description of his symptoms and performed a rectal exam to diagnose him. We asked him to do an x-ray to rule out stones which he did. We were hopeful that it might be something curable. Dukie is taking a steroid to try and shrink the tumor and an antibiotic. I thought at first he seemed to be getting better but now I'm not so sure. I'm not sure if it's the medication or just the fact that he's sick but his eyes look so cloudy and he's doing a lot of sleeping. He's also trying to urinate every few minutes. I noticed that he's starting to shake like he's afraid. It breaks my heart to see him like this. I'm supposed to bring him back for a check up to see if the tumor is getting smaller next week. I feel so bad for him because he's a huge part of our family. He grew up with my kids from the time he was a puppy. I don't want to lose him but I don't want to see him suffer. I know he's uncomfortable and scared. How do you know when enough is enough?
