dev if your getting meat, ie cow meat , hores meat, lamb, or goat, from the knackers yard, make sure you find out if the animal died naturally or was shot , if it has been put to sleep by injection stay well away , i have alot of horse, cow, lamb meat from the knackers yard , i always ask how it came in and how it was killed .
i had a mate who gave his dogs horse meat that was injected and they died, it might have been just a one off mate but dont risk it .
