I was not a dog person was badly bitten as a child and my mum stopped letting me near dogs. The result being I was terrified of dogs when I saw ds was getting scared we got a dog.
Fast forward our dog is 9 months now fitting in well and generally happy. However dd is mobile now and seems interested in the dog what sort of things will bug him. Having no knowledge of dogs the only sign I have seen for him being annoyed or fed up is he walks away and sits by me, are there other signs that he is not happy.
