Nostalrius Begins - Quality wow vanilla realm (1.12)

So I just hit level 10 and tamed my first pet. I made the mistake of not keeping a watchful eye on his happiness level and he ended up leaving me. The problem is now whenever I try to tame another pet the cast finishes and does nothing for gives me error text saying "You have an active summon already". Anyone have a solution for this? I'd rather not have to re level.
