Here's my favourite (shussh, don't tell the others). Milo is a labrador cross that I rescued from the RSPCA 6 years ago when he was 7 months old. Marley had nothing on Milo when I first got him, he was definitely the worlds worst dog! 6 years later though and things are very different, he's a fantastic dog now.
Milo is a beautiful dog! My previous dog was a Lab. I wanted to tell you that it wasn't just your Lab who was bad. Mine was terrible, too. I think in the first two years she managed to do every bad behavior puppies will do. She turned aggressive at 6 months. It took quite a bit of training, but somewhere between 3 and 4 she pulled out of it, mellowed out, and turned into the wonderful dog that Labs are known for.
Thanks for sharing your photographs of Milo. Milo seems to be a really happy dog and seems to be smiling in all of the photographs. Don't worry your secret is safe with me. I won't tell your other dogs. The other commenters are right by the way! What a lovely landscape.
