Why is my 11-week puppy lethargic, not eating, and peeing herself?
Thanks for visiting Petco Pet Education Center, formerly Petcoach! Based on your description this could be a number of things. She is a large breed growing puppy so they often go through spurts of sleepiness where they may not eat as much of their food. With that said, this should then be followed by a spurt of activeness and engorging in her food, within a 24 hr period. If she is lethargic and not eating well for more than a day, then she may have an infection and should be checked out by your vet asap. Pets also don't often pee on themselves, even at this age. This concerns me for a possible urinary tract infection, which causes her to have an inflamed bladder, which then causes her to not be able to pee in a designated area. At almost 3 months of age though, she may still be potty training.
At any rate, it is best to get her seen with such vague symptoms, just to make sure she doesn't have an infection and to get her treated right away if there is one present.
I hope that your fur baby Sansa feels better soon! Best wishes and take care.
