I'm being positive and very hopeful, anyone know where I can get a plastic paddling pool for my dog for the summer. I might as well ask now so I can start to look

Are you looking for one that doesn't need inflating and keeps it's shape?

Yes the plastic solid type

Argos???

Not sure about solid paddling pools but you can buy solid plastic sand pits which work really well, also from Argos

As others have said - Argos. I bought the sandpit which is (I think) an apple shape, and comes in two halves. Although I do think I'm the reason we haven't had any decent weather in the summer for the last 2 years - I bought this at the end of the last nice hot summer in preparation for the following year, as it was sold out everywhere I tried when it was hot. It's not been hot enough to get it out since!
