Hi! I've had a few labs now but have never had food protection issues. Recently though 2 of our labs have started fighting each other over food. Charlie we removed 2 and a half years ago and is food obsessed. Will blatantly steal anything! He's 6. He's always warned Tilly (1 year) off if she approaches his food but now I guess adolescence has kicked in and she fights back. Both dogs are fed from the special bowls to slow them down as the hoover their food up. After the last incident we started feeding them in different rooms and don't allow them into each other until bowls are cleared away, but tonight they fought when we were eating. Hain't dropped anything and didn't see it coming. The aggression is not (thankfully) aimed at people although I've been bitten separating them. Any suggestions? Thank you!
