I have one too..... each day I put his food out I never know if he will eat it..
we have just been though a bad couple of weeks with one of my bitches in season.. so he was fed chicken, fish, steak (cooked) (not all together of course) with oil then I pour the oil over his naturediet and mix in the meat... then cover it with strong cheese... all this just to get him to eat ... he lost a bit of weight but now that the season is over he thankfully is eating his food again, we dont have a problem with the bile with him .
I do find sardines mixed with the dog food goes down well.
my vet doesnt believe in giving zantac ... he told me when I had a problem with bile with one of my other dogs... to change the food and give probiotics

He doesnt eat as much as I would like and is in my opinion too thin... it can be soul destroying ... I would much rather have a fat dog that needs to loose weight!
