Training an animal can be an exhaustive process, even for the most patient of pet owners.
And, as these creatures prove, there are some that just can’t be tamed.
A hilarious new gallery compiled by BoredPanda reveals nature’s naughtiest critters who have been caught getting up to no good.
Proving rules are made to be broken, one rebellious dog is pictured making off with a sign that banned pooches from the beach.
Meanwhile another cheeky mutt was sent outside after clambering on the table, only to sit on the garden table in protest.
A cheeky pigeon wasn’t worried about minding the gap as he ignored signs to stay behind the yellow line at a train station.
Elsewhere, another bird showed off its rebellious side in a snap that saw a peacock passing through a door clearly marked ‘no exit’.
