Adjustable Mini Pig Harness also fits other pets (Potbelly pigs, ferrets, rabbits, dogs, cats). Total length of the harness is 8'5". If you are purchasing this harness for a pig it will fit a piglet all the way up to a 150 pound pig. If you need a larger harness contact me directly for a custom order. Harness Instructions: I pre loop the harness for a faster process but adjust it first to the size you think you need before placing it on. Place the large loop around the head and body just under the front legs. Place the small loop around the head. Use the pulley to make the final adjustments to the size once it’s on if you choose too. If you want to keep it loose you do not have to use the pulley. Piglets and young animals will take some time to harness train with any harness. This is the best harness I have used. My pigs won't wear a thick harness with a buckle and I won't use a rope harness that rubs the hair off my pig. This one seems to be perfect. If your harness comes out of the ring it’s very easy to put it back in just take the end by the ring and pinch it together to make a loop and poke it thru the ring. Adjust the loop size after. A pic will be included in your package along with instructions. The harness is built this way so the size is adjustable. Instructional videos are posted on the Amazon ad. If you don't see it try choosing a different color it might be visible there. Please call or contact me directly with your email address if you need any further assistance.
