Nintendogs Labrador and friends Hints

Well I have heard that before you go on walks you need to change your clock to the clover clock and put a lucky collar on your dog. Supposedly your chances of finding a rare gift will increase by %10. I tried that but I only found more dogs than presents.However, I did find a gold bar and a meteorite. I cannot confirm, nor deny that the clover clock and the lucky collar work.
P.S. Your dogs CANNOT have puppies. Also, your dogs will never die and are locked in the puppy stage of life. I discovered this during some research!! ;)

I do not know if this is true but i heard that
very rarly a parot will appear juring a walk give it something worth 200 pound and it will give you a gold bar

note:worth 2000 pound
