When the weather warms up, I thought it might be nice for our golden retriever to be in the garden with a kennel when we're out, rather than in a crate inside. It would presumably be a bit less boring and he would be able to pee and poo at will. The previous tenants have left a fenced area about 3x3m where they had a kennel, though there's no real reason for him not to have the run of the garden, which is completely fenced, except that he eats the plants.
What do you think of kennels and dogs being outside? It wouldn't be that difficult for a thief to get in up the bank at the back of the garden and over the fence, but it would have to be a well-planned dog theft as hardly anyone could actually see him in the garden. I think it's a very small risk.
