Hey i know this may be the most simplest thing but im new to all this puppy stuff.. my pup hasnt pooped at all today, yesterday she had about 3 which was good and her last poop was last night but nothing at all today and its now been almost 24hrs since her last poop. shes 8 weeks and ive had her home for 3 days now.. could this be related? is there anything i can give her to make her go? shes not looking in a bad shape. still playful as ever and hasnt tried to go and strained if you know what i mean... should i be concerned about this?? sorry for the silly question!!
