My cocker spaniel 8.5 years old has been diagnosed with colitis and he's had this for about 3 months or so. He's been on two courses of anti-biotics and is now on the Science Diet I/D strictly for over a week. However he's not getting better - he cries when he tries to poo and when he does poo, it's soft and has blood at the end of the stool. This lasts for a few seconds and then he's fine - happy, etc. He's also eating normally and hasn't lost weight. A stool test came back normal but showed signs of some Malabsorption, hence the Science Diet. The vet is convinced that it will rectify itself overtime on this diet, however my dog is in extreme pain when trying to poo. Any advice or suggestions please or should I go for a second opinion?
Many thanks
