Hi! Congratulations and Happy Birthday as well!! You must be a bundle of excitement over THIS Birthday gift!! I feed both of mine Wellness Super5mix, it is Whitefish and sweet potatoe. They love it and are doing well on it. Like everyone has said, dont do the switch to anything right away. As far as the spray, by two years i wouldnt think you would need it. My Oliver is just about 2 and he doesnt chew on anything but his toys. (but then i guess that it is all in how they have been trained) Did she tell you that this one is a chewer? Bully sticks are the greatest thing and they all seem to love them!! Anyway, cant wait to see pictures! Good luck tomorrow!
