Dexter eats absolutely everything he can in the garden. He will put anything into his mouth, chew it and swallow it- grass, leaves, petals, fir cones, bird poo, plants etc. It is making going outside rather stressful as he thinks it's a wonderful game dodging away from me while I try and grab whatever he's put in his mouth. He will not be distracted by treats or toys. Does anyone else have the same problem?
