I knew it, I knew it! I have just googled ‘Portuguese Water Dog’ and this is what I found:
The Portuguese Water Dog is a water-loving, lively but loyal dog. Affectionate and fun to be around, it is excellent with children and usually gets along with other dogs and pets without any problems. It has a stable, pleasant temperament.’
‘Bear in mind that this extremely intelligent dog will take liberties if it feels it is stronger minded than it's owners. Make sure you are consistent, firm and confident in the way you handle the dog. This breed may out-think its owner! Generally willing to please, this is an obedient dog. Spirited, with great stamina, yet calm. Portuguese Water Dogs have a super sense of humor and love to be in the spotlight of attention.’
Water-loving? Check! Lively? Check! Taking liberties? Check. Loves to be in the spotlight? He can't bear it if he isn't. OK, so the bit about obedience doesn’t quite ring true but everything else does.
