What wrong with my puppy?

My puppy hasn't eaten in 2 day and hasn't pooped in 2 days

My puppy is sleeping a lot,whining,will barely eat and doesn't like to go outside.what's wrong with my puppy?

12 week old boxer suddenly lethargic, won't open her mouth, moves away when we try to touch or look at her mouth, jaw, neck or throat...didn't see/hear her injure herself. when she does open mouth to yawn, it seems to tweak her neck somehow.

My friend has a puppy that is 11 weeks old and the last few days the puppy has been throwing up and not eating much at all, her poo has been runny and yesterday it turned a white coulour with a little bit of blood through it, she has also been very weak and larthargic but last night she started to...

she is not eating, she seems to want to, she is always shaking, her eyes don't want to stay open, she does not want to stay awake or hold her self up and she constantly crys, and she has bloody diarrea
