yvonne dallas, TX 3/15/2010 8:50:54 PM every since we had our dog martha microchipped, she has lost almost all her hair and is constantly itching. i never gave it a thought untill my brother brought it up. the vet has no clue what is wrong , the only thing they say is she is allergic to something. it has to be the chip. i have not got the money to get it out and so i am gonna have to put her down to releive her suffering. ohh and she has 2 of them in her cuz the first one got lost in her. it is the only thing i have left. we have had martha for 11 years and we are gonna be very devastated to loose her but i dont know what else to do.
