Hi Bens mum, Marti, my springer had this three times. It looks worse than it is, and lasted about a week the first time. A yearlater she had it again , leaving a tilt, but followed by the other side so she evened up. She also had a heart murmur and the strain of moving around feeling dizzy in old age wore her out.
Things that help enormously......a raised bowl for feeding and drinking, or putting it on a step. I took her outside with a scarf or towel wrapped underneath her tummy to help lift and keep her steady.
Love to Ben x
