Puppy urinating problem..?

[Tami Satchell]

My staffy cross pup is 10 months old, and recently she seems to be peeing less and less! She goes for five or six walks a day, but has recently started holding it in till 3 or 4pm. I have read loads on the net that talks about serious conditions such as bladder infections and even cancer... but she has no problems such as straining when she does pee, there's no blood in the urine, everything seems normal. She has access to plenty of water, and doesn't seem to be drinking any more or less than usual. She's happy and bouncy and just her normal self!
Is this a problem I should be worried about, or is she just holding it in for some reason?!

Maybe just growing up, bladder getting bigger, she can hold it for longer? My fellas will hold it for hours until they can go on grass.
Pop her to the vet if you are concerned
