Thanks to all who replied and offered some great advice, I'll look into all meds suggested and keep for future reference. The great news on Trix however is that after a 24 hour fast, and after consuming poached cod and pasta for the following 24 hours [1 small meal and the 2nd slightly larger - preceeded by some ANTEPSIN 1 hour before each meal] Trix produced a solid, firm, very normal looking POOP!!! It was 2:45am this morning and I ran out to inspect said stool and found to my complete delight that her upset tummy was gone!
I'd tried the 24 hr fast followed by bland food last week [when her tummy was upset] but it didn't help on that occassion - I think she'd caught a tummy bug from Lula [my 3 year old JRT] but that Trixie's weakened immune system took longer to fight the bug. Lula bounced back and was passing normal stools within 2 days!
Today I started adding a tiny amount [about 1 forkfull] of the HILLS n/d diet to her fish and pasta, over the next 7 - 10 days I'll be adding a little more hills and a little less fish/pasta until she's on hills alone - it contains white rice so hopefully that'll help prevent any runny stools in future! It's a very finely balanced diet so I don't think I should add anything to it.
I'm trilled as this now means I can resume her PIROXICAM every other day [for the time being - increasing it to a daily dose in 2 weeks] again with the antepsin given 1 hour before food and CYTOTEC [Misoprostol] given WITH her food.
I'm so relieved and hope I'm not tempting fate by saying that at long LAST - nearly 3 weeks after her TCC diagnosis - Trix is now being treated for this evil cancer. Everyone who knows and loves Trix is rooting for her, and including her in their prayers. Trix, Hubby and myself are all very grateful for that!
I'm also [now Trixie's tummy is now settled] going to be introducing her herbal treatments. I found out about a herbalist in Australia via another canine cancer forum. His name is Robert McDowell. I read the testimonials on his site and decided to give them a try. He makes a powerful antioxidant - the main ingredient being maritime pine bark. This is said to boost the dog's immune system. His website can be found here: www.herbal-dogkeeping.com if anyone would like to find out about his treatments. I'll start Trix on these 2 herbals once I'm confident that her system is dealing well with the piroxicam.
When I spoke to my vet about Trixie's runny motions, she suggested keeping a diarrhoea treatment on hand in Trixie's meds box - KAOGEL - hopefully I wont be needing it, but I think it's a good thing to have just in case!
Once again, thank you to everyone who took the time to reply to my question - I wish you and your 4 legged babies a very healthy and happy and positive week ahead.
