Ive been living here for a year and never had any problems with my dog going out in the garden. He usually sits out there for hours and have to force him inside. Over the last three weeks he will not go in the garden or on the grass which is stopping him from going toilet. He runs inside and will refuse to be let out in the morning. Ive mowed the lawn and tried teasing him on with ham and treats. It took an hour then he bolted off in doors again. After mowing the lawn i can smell and taste a strong substance and is making me wonder if anyone may have done this on purpose. I have a neighbour who returns home gone 11 at night. Really chavy! Music blaring etc. And does anything to wind the dog up (get him barking) once hes achieved this he'll moan about him barking. Not pointing the fingers but just an option? My dogs been sick twice in the last three weeks and has become unhappy. Any help would be great!
