My 12 week French bulldog pup has become extremely fussy with his food after having his 2nd vaccination and microchip last Thursday. I have been feeding him Royal Canin (as recommended by the breeder) and started the change over process to Millie's wolfheart which was going very well until Thursday. Now he doesn't want either food. I've been wetting with warm water and picking the food up after 10 minutes and still no luck. I've also tried to entice him with minced chicken and tripe and he still isn't interested. At best he might eat a very small amount but nothing more. Other than that he is absolutely fine- running around playing, drinking etc but I am getting a bit concerned as he was a hearty eater before and is starting to lose weight. I don't want to change his food as I really don't want a fussy dog when it comes to food.
