8 month, recently spayed cavapoo sick

Good morning guys! I’m posting for my mom.

Age: 8 months

Weight: 12 pounds

Breed: Cavapoo

Spayed: Yes, 4 weeks ago

Symptoms: Leaking diarrhea, throwing up bile, pain in stomach. Drinking water and eating. Since yesterday. Very sleepy. Doesn’t play.

Comments: She just came back from a doggy daycare for a week as of 4 days ago. She’s never been sick before. She is very spoiled and well-cared for, and my mom is freaking out.

Location: ATL, GA

Questions: What are your preliminary thoughts, and should we go to an emergency vet right away?
