Alter Pet

Your pet takes a different form. When you cast the spell,  the effects of which last until dispelled. 

Change Appearance. You transform your pets appearance. You decide what it looks like, facial features, sound of its voice, hair length, coloration, and distinguishing characteristics, if any. You can make your pet appear as another creature, though none of its statistics change. You also can't change its size, and its basic shape becomes that of the new creature. 

This spell only works on creatures with animal intellegence of 4 or lower.
