Wow! All the pictures and videos posted above prove that really good results can be achieved!
We also made agility until he was almost 1 year (low level "puppy" things…in the video you can see the first "steps" starting from the easiest "White Field", then the "Yellow Field" etc..till the most complete and "difficult", which is not in the video), and he really loved it. Afterwards, when he began to grow up we changed sport and we opted for IPO training.
What I noticed is that they learn everything more rapidly than other breeds…but they are not as reliable as other breed … if they decide that they want to follow a butterfly it's really difficult to make them concentrate on the training. But I believe that it's a really good training for the dog and for building up a good relationship.
I also believe that it's a sport particularly indicated for dogs who need to become more self-confident
