alright last night i took him to a different vet that i usually go to. anyway they did another examination (which tyson didnt like) and the vet came up with the possibility of OCD. i wanted to do the x-rays but they were just too expensive. so i called my vet today and told them that i just wanted both of his shoulders x-rayed and possibly his elbows so we scheduled an apt. for thursday. right now he is on a glucosmine pill but from the info that i read on the interet glucosemine has never shown any scientific results that it will actually work. lets just hope that this site info is out of date. if he does have OCD i will not be able to afford sergery which is breaking my heart because i will not let him suffer...i would like to know if any of u have had to deal with this OCD and if so how did medical treatment work for ur dog??
