I've been working on developing a pet specifically for the Arena. I want it to have Spell Proof and Spritely. So far I've mixed a Spinyfish, Sea Dragon, and Fierce Hound to make a pretty studly looking Fierce Hound. I began training him and feeding him crafted Cereal Snacks. So far my experience had been, and most of the information I'd read was, that all pets liked these snacks, and loved them if they were same school (ex. Sea Dragon is a Fire pet and loves Sizzle Smacks, a fire snack). The Fierce Hound though only likes Raising Bran (the death school Cereal Snack) and doesn't like any of the other crafted Cereal snacks. I'm wondering if anyone else has had this issue before and if this is a bug.
