Could you please tell me whether your fleece harness would be suitable for tracking?

I have a 2 year old GSD and would like to start tracking; both of us are complete novices at this!

Yes, there is no reason why you cannot use the fleece harness for tracking - the large neck opening means that when the dog has its head down it will not be hampered with a strap going across the front of its neck and annoying it (as some designs of harness do).

Traditionally Working Trials handlers use leather harnesses but I am more than happy with these fleece ones as they are soft on the dog's body and are washable in a low heat wash in a washing machine. You will probably need the 65-90cm size but measure your dog behind its front legs to make sure before ordering.
