Hi everyone,
This is my first post on the site, so hope it all goes to plan!

I have looked at a number of posts concerning Colitis and IBD but just wanted your advice, please.
We had our now 20 month old Cocker, Otis, from 9 weeks old.
Since he was about 6 months old, we have had problems with his tummy. His morning stool would be fine, then as they day would progress, his stools would get more and more squidgy.
We agreed with the Vet to just keep him on his kibble (RC at that point in time). During last year, we had several visits to the vet, where Otis' had such loose stools, which we could not fix ourselves. On two occasions, stool samples were collected over three days and analysed but came back normal. General blood tests were taken and were also normal. Despite this, Otis was put on Metronidazole for 10 or 14 days just to make sure. At all times, the tummy would settle on the medication but the stools would turn loose again after only days or weeks.
On most occasions, Otis is happy and alert and his bowel movements are controlled, so not generally accidents, if you know what I mean. Still, though, I am at home most of the time with him so I take him out regularly.
Come December last year, I went to the vet and said that I just was not happy with the stools he was passing. They would contain mucus and also blood stains at times.
The vet said that he was quite sure he has IBD but would need to do a biopsy to confirm.
What we did in December was to put him on a hydrolysed protein diet (Specific COD HY Allergy Management Plus), which is a dry kibble specifically designed for dogs with IBD. We agreed to only give him this and NOTHING else at all. The first 3 moth of this year, his stools have just been amazing!!! Firm all through the day no matter what and I thought we had it sorted.

HOWEVER………, this was not to last . Again slowly, we have seen the return of stools going softer as the day goes on and the mucus + blood stains returning. May this year, he had a bout of bad watery bowels where we managed to turn him around for a couple of weeks but then it returned and once again we had to go to the vets to get him on antibiotics to try and solve it. This time again it cleared up OK but one week after coming off the antibiotics, his stools are very, very soft and slightly blood stained. This is where we are today.
My question to you is, whether there are other tests I should have done before we turn to the biopsy?? I don't know why but I feel so saddened to think of having this biopsy done…… I guess I am worried by the potential lifelong medication he might be subjected to as well, such as steroids. I am also worried about putting him under if it can be avoided.
-Has anyone had experience with the hydrolysed foods and would it be worthwhile trying another? What about allergy testing? -the food he is on, although it contains hydrolysed salmon, the rice is not hydrolysed, so perhaps he is allergic to that? I can see that some people have x-rays and ultra sounds carried out but am I just putting off the biopsy adding further costs for us?
Otis’ brother also has a sensitive tummy and his stools too go softer as the day goes on but not with mucus or blood stains and not as many bouts of true tummy upsets which cannot be turned around without medication. -They do not feel like it is a problem generally the way we do. In their opinion, a biopsy is very extreme.
Sorry for the long post, I just don't know what to do for the best! I know it sounds daft but his stools are taking over our life! –Every time someone takes him for a walk his stool get a mark out of 10!! I am just so worried about him and that I am not doing enough to help him.

I do have an appointment to speak to my vet again tomorrow evening. I just would love to hear some advice on how others have been able to manage this problem. Can they still live a happy life with this problem? I know he generally seems very happy and not bothered by it but I just think it is not right with mucus and blood stains, it must be sore, the poor thing.
Hope all you knowledgeable cocker owners have some advice.
Anette & Otis
