my dog is 10 months old now and still wont jump wired fences or anything he can see through but when he was 4 months he tried jumping my mesh out garden to get out was pretty high and caught broke his toes because he got caught on way over but his confidence as grown and is trusting me more every day and he has now started jumping up on 5 foot walls on his own i did not teach him he randomly started jumping up little walls then one day jumped up the 5 foot wall. i am now thinking of starting him on wired fences or any fences any ideas how to start him doing that??
