Amazing how dogs sense when their owner/friend is not 100%. They add so much to our lives.
Sarah honey, drink lots of water, think about a stool softener and lots of fruit and fresh veggies... You need the fibre and replenish the water to flush through the drugs. It is also a good idea to add a little pure apple juice or even lemon juice to your water because quite often the water doesn't absorb into the cells, the added glycogen in the juice helps the cells retain the fluid.
Babbling here.... Google 'water, water, heals.' There was a Dr in the second world war who found that so many prisoners were dehydrated and when fluid levels were restored, all sorts of ailments were helped.
I will post his name next time, I get on the net.
