Has anyone elses dog become really clumsy and does silly things without thinking when they are around a year old? is this just a transition phase into adulthood? I'll explain: Holly is now 11 months old and over the last few weeks she has been a bit clumsy and not thinking before she acts. She keeps mis-judging things when she jumps so she half lands on stuff and then falls off, or when she is playing chase with the cat she will crash into stuff when turning. Or sometimes she's just sitting on the arm/back of the chair and falls off. On walks she sometimes jumps off banks without looking first, nothing bad has come of it yet but I nearly had to catch her once as she hurtled towards me from on top of a bank that was level with my head, but then she curved away from the edge at the last second. Then on wednesday she was playing with a large dog and its owner threw a ball and the dog ran straight into Holly. Holly screamed more than I've ever herd her scream and wouldn't put her paw on the ground, I thought it was broken so I carried her home and by then she was fine and running around again. Then today we were at a different park that has a stream running through it and she fell down a bank into the water because she lost her footing (there was also another dog blocking her a little) and she couldn't get back up the bank so I had to call her over to a lower part. She scared me so much, I was imagining her hitting her head on the way down and drowning etc until I could see her again. When we got back to the top she nearly did the exact same thing again. So is she just not thinking or what? has anyone else experienced a dog somewhat losing their brain when they are around this age and doing really dumb things?
