First of all, thank you all so much for your response and great feedback on Kona's Chips! I know it probably sounds silly but it feels "supportive" in this that we are going through with our little "junkie"!!

I know I will never, ever even
try any other kind of chicken for Toto. She will be eating Kona's Chips when she is a little old Yorkie lady!

I totally trust them and I never want to go through anything like this again.
UPDATE on Toto
. She has calmed down some but acts like she is starving all the time. I cannot increase her food quantity until her vet and I have a chance to go over everything and plan. She will be spending the day with him on Wednesday and he will be doing every test they are capable of doing and it will be sent of the University's lab. He trusts their results more than their onsite lab or anyone in the country, so we are comfortable with that. It will take longer and be more expensive but at this point, the results are all we are concerned about. I will certainly update you all ... hopefully he will just find that Toto is just a little piglet and Patrick & I are just upset for no reason!
