Well it is sort of DIY... :D
We have a young dog which has developed some neurological problem, as yet with no definite diagnoses. For a time she was completely unable to even walk, but has either improved or learned with time to better control her limbs.
Her favourite pass time has always been chasing anything which moves, bubbles and laser spots. We have bought her several of those kids bubble guns, squeeze a trigger and bubbles are blown out. Rather leaky, poor quality and they don't last long. We have now bought her one of those mains powered units which you can simply leave running, no leaks and it works every time.
The idea is therapy, to improve her mobility on her legs.
Rather than find, buy and lug home great big bottles of bubble solution (mostly water), is there a way to make this stuff from home ingredients?
I have tried Fairy liquid, which was useless.
Cheers...
