People use bbq for outdoor cooking and they use steel brush to rub the oil off bbq. This is our lesson, we will buy new steel brush every year and threw it away used one. The one we had, it somehow fell off to ground and our little dog look for anything to lick off the ground where bbq was alike oil drip out of bbq and she found one wire (from steel brush) with oil on it. She licked and I guess she swallowed it. Now we have to pay 1600.00 bucks for it to remove from her. GRRR. We always had those brushes years and never had a problem till this now. Thank god she made it thru surgery today, we will pick her up tmw. We miss her so much and cant wait to bring her home. Thanks for reading......
