When was she last de-wormed?

As for the eating poop. What food are you currently feeding? how long has she been eating that food for?
Some puppies go through a phase of poop eating, in which case the only thing you can do is not give her the opportunity to gat to her poop (clean it up as soon as she does it).

Otherwise, it could be that she isn't digesting properly, this could be for a number of reasons:
1. She is eating too much so not digesting it fully and it comes out still tasting (and looking) like kibble. If her poop looks similar to kibble that has been soaked in water and then pushed together, this is most likely the reason.
2. The bacteria in her digestive system isn't sufficient (this is usually only the case after very severe worm infestation, a stomach blockage or an operation on the digestive tract). In this case a little plain yogurt would do her good, or a dog food with added probiotics/prebiotics.
3. She isn't getting enough nutrition from the food, so tries to re-digest it to gain more nutrition (this can be for a number of reasons, but will also have other signs, she will get skinnier and tire easily for starters).
4. She isn't getting enough food and is still hungry (this could also be happening if she has intestinal worms taking all the nutrition from the food).

I would start with de-worming her (if she hasn't been dewormed in the last month, not including heartguard) and see how it goes. Also try to clean up the poop as soon as she does it to make sure this doesn't become a habit.

I don't know what food you are feeding, but if it is a good quality food, changing it shouldn't be necessary. There are some other things you can do, but we should find out the cause first .

maybe ur sunshine is acting only la...

i've asked my vet about this before as one of my poodles had the same condition as yr sunshine and my vet told me that this is common due to the joints on their legs or sth like that dont really understand her when she started taking out the skeleton photo of a dog and educate me on their bones structure so i stopped her n said as long as she's fine , i dun need to know further. lol

so yeah as long as she's not in pain she should be ok
