Why is my 10-month-old dog lethargic, shaking, and has a dry mouth?

Pet's info: Dog | Maltese | Male | neutered

Good afternoon, I’m concerned about my dog he’s about 10 months . He’s usually energetic and playful but lately he’s been sleeping a lot and seems a little down. He also shakes sometimes and seems like has a dry mouth! If you may please!

It sounds like Mylo is lethargic, and lethargy is a sign of illness. Unfortunately it's a sign of many illnesses, like a systemic illness, infection, or injury. Without seeing him in person, I can't say what is going on. I'd have him seen by a vet in the morning for a health check.
