A lot of people have problems with on Wellness. We had Gator on Wellness Puppy first and his were never firm which is one of the reasons we switched. I am not sure what you have available in your area but there are several foods out there that might work better. I use Fromm Beef Frittata and it works well for us.
There is a good chance that if you find the right food, those problems will clear up. Good luck and keep us posted on your progress! We have to be with these guys.
