Call first before choosing observation
Call promptly for watery stool, repeated vomiting, poor intake, or behavior change, especially with incomplete or unknown vaccines. Do not wait for blood; infectious illness may begin with reduced energy and appetite.
For unsteadiness, collapse, marked weakness, abnormal breathing, or severe belly pain, contact emergency care immediately and arrange safe transport. If water is repeatedly vomited, contact a vet immediately for triage. Do not test recovery by forcing food, water, or medicines.

What “vaccinated” needs to include
Provide dates, products, and clinic records or photos for each vaccine. Say when records are absent. For a recent arrival, include the previous home, travel timing, contact with sick animals, and illness in littermates.
Canine parvovirus and feline panleukopenia require species-specific assessment. Smell, vomiting without diarrhea, or one home test is not a reliable clearance; the veterinarian must interpret history, examination, and testing together.

Make “ate a little” useful
Use the usual bowl or measure to note food offered and remaining, including access by other pets. Record the last voluntary meal and drink, vomiting/stool episodes, and urination. Describe rather than invent milliliters.
These notes explain intake and losses; they are not a home dehydration score. Moist-looking gums or a brief period of play do not prove hydration or blood glucose is normal.

Tell the clinic before entering the waiting room
Tell the clinic “young pet with vomiting/diarrhea; vaccine status uncertain” before arrival and ask about entry and waiting arrangements. Avoid shared bowls, litter boxes, and toys; wash hands after waste handling and record each animal separately.
Stronger disinfectant is not automatically better; some viruses resist common cleaners. Ask the clinic for a product and contact time suited to the suspected pathogen and surfaces, and never mix cleaning products.

Avoid adult-pet shortcuts; agree follow-up
Do not impose prolonged fasting or use human anti-diarrheals, leftover antibiotics, or dewormers to guess the cause. Home care, feeding, and rechecks need a veterinary plan for this animal. Unweaned pets need separate advice.
Before leaving, repeat the feeding/medicine instructions, return-now signs, and backup clinic in your own words. Keep written instructions with the log. The symptom tool cannot replace this individual plan.
