Until this year, my dog was a shaking, drooling, inconsolable and very scared animal. This would be for a good 2 weeks in October and a further week in November. Walking her was difficult as the first hint of noise and she'd be violently trembling, and be off...sometimes aware of the noise well before weaker human ears. This would continue as the New Year got closer.
I wouldn't wish that on any beast.
I do 60% of my shopping at Sainsbury...never any doubts about quality or price.
