In september last year my 8yr old springer x whippet spent 8 days in the vet on a drip. Hes fine now but since coming home he is so so stressed over the slightest noise esp from neighbours (we live in a block of flats) If they close a door, even gently we can hardly hear it but he just wants to run and hide. Its worse at night as the neighbours dont go to bed till late. They are certainly not noisy but its the SLIGHTEST sound. Our sleep is being disturbed badly with him. We have tried leaving music on but he can obviously hear above it. We have a DAP plug in and a calming spray and neither makes a diff. I would really appreciate some feedback x
