Our 3 year old TT has been an absolute pain over Christmas, up until now Coco has always made a big fuss when we have visitors, but when they have made a fuss of him, he would go away & lay down quietly. but over Christmas whenever the family or friends came, he persistently barked, without giving up, I tried putting him in the garden, stroking him, leaving him in the kitchen with a hide, but he carried on for hours. Please can someone make a suggestion as to how to calm him down. He has always given everyone a rapturous greeting!
