I've never really pushed him to use it but have seen many who ride well and those humans who have them have always said the bigger the better. Buster mainly uses his as a chew toy, he's had three and has eaten the other 2 LOL!! There are a bunch of different sizes yes. I love when he gets mad at...
Fromms has a four star grain free line that is better then just about any food out there. Sometimes the grains screw with these babies. Also do you give her yogurt? Some people use it to cut back on farts lol. I know how bad they can get and how it can make your eyes burn sometimes. :ROFL:
Hopefully the doc will get it under control. If I were you Id launch an outright Vetricyn attack on it. This has happened twice to Bust and both times I attacked with it and it worked no soaks nothing but Vetricyn. It really is amazing and I swear by it. That pic of him yawning is classic :D
