When Should You Get in Touch with a Veterinarian About Your Pet’s Health?

It’s 9 p.m. and the dog has thrown up twice. He’s wagging, drinking water, and looking at you like nothing happened, but something in your gut says this isn’t the usual grass-eating episode. You pick up the phone, put it down, search for the symptom, read three contradictory answers, and put the phone down again. Every pet owner knows this moment. The problem isn’t that you don’t care; it’s that you don’t know whether this is a “watch and wait” situation or a “get in the car” one.

Pets can’t tell us where it hurts, and they’re good at hiding it, so the decision to call a vet usually comes down to reading signs. This guide sorts those signs into four levels of urgency, from  call right now to mentioning it at the next check-up, so the next time you’re standing in the kitchen with the phone in your hand, you’ll know what to do.

Many Pets Aren’t Seen Often Enough

The hesitation is common, and it shows up in the numbers. According to the American Veterinary Medical Association, only 74.2 percent of dog owners and 57.3 percent of cat owners took their pet to a veterinarian in the past year, and the share who said their pet simply didn’t need a check-up nearly doubled between 2023 and 2024.

Cats in particular are under-seen, largely because they hide illness so well. Knowing the signs below is how you avoid missing something that would have been easy to treat early.

Level 1: Call Right Now, Day or Night

These are emergencies. Don’t wait for morning, don’t search online, and don’t try a home remedy first:

• Difficulty breathing, choking, or blue or pale gums
• Collapse, inability to stand, or sudden paralysis
• Seizure lasting more than a few minutes, or repeated seizures
• Severe bleeding that doesn’t stop with pressure in a few minutes
• A bloated, hard abdomen, especially in a large dog that’s retching without producing anything
• Known or suspected poisoning: antifreeze, rodent bait, chocolate, xylitol, lilies for cats, human medications
• Hit by a car or a fall from height, even if the pet seems fine
• A male cat straining to urinate and producing nothing
• Eye injury or a sudden bulging, cloudy, or painful eye
• Heatstroke: heavy panting, drooling, weakness, and a body that feels hot
• Difficulty giving birth

If you’re unsure whether something is an emergency, that uncertainty is itself a reason to call. A good clinic would rather answer a question than treat a delay.

Level 2: Call Today

These aren’t minutes-matter emergencies, but they shouldn’t wait until next week:

• Vomiting or diarrhea more than twice in a day, or any vomiting with lethargy or blood
• Refusing food for more than a day (cats: don’t let it go past 24 hours)
• Sudden limping or crying out when touched
• Straining to urinate or defecate, or going far more often than usual
• Excessive thirst or urination that started recently
• A wound, bite, or abscess, even a small one
• Coughing that’s persistent or worsening
• Swelling anywhere, especially the face
• Scratching, head-shaking, or ear odor that’s suddenly intense
• Noticeable behavior change: hiding, aggression, confusion, or restlessness

This is the level where most “should I call?” questions land, and the answer is yes. The point of a same-day call isn’t always a same-day visit; often the clinic can tell you what to watch and when to come in. The easiest habit to build is to get in touch with a veterinarian as soon as a symptom crosses from “odd” to “concerning,” rather than waiting to see if it gets worse. 

Van Dyke Animal Clinic, for example, lists emergency care alongside its routine services, which is the kind of setup to look for in a regular vet: somewhere you can call with a question at 4 p.m. and be seen if the answer is “come in.” Whoever your vet is, save the number in your phone and know their hours and their after-hours arrangement before you need them.

Level 3: Book an Appointment This Week

Slow-developing changes deserve attention but not alarm:

• Gradual weight loss or gain
• A lump that’s new, growing, or changing
• Bad breath, red gums, or drooling, which usually mean dental disease
• Dull coat, dandruff, or hair loss in patches
• Stiffness getting up, reluctance to use stairs, or slowing down on walks
• Mild but persistent itching
• Changes in sleep, appetite, or interest in play over a few weeks
• Accidents in the house from a previously house-trained pet

Many of these are the early signs of conditions, from arthritis to thyroid disease to kidney problems, that are far easier to manage when caught early.

Level 4: Mention It at the Next Check-Up

Some observations are worth noting but not acting on immediately. Keep a short list on your phone:

• Occasional soft stool that resolves on its own
• A single episode of vomiting with no other symptoms
• Minor changes in how much water they drink in hot weather
• A small, stable skin tag or wart on an older pet
• Slight grey in the muzzle and slower mornings in a senior

The list makes check-ups more useful, and sometimes a pattern you didn’t notice becomes obvious when you read it back.

The Check-Ups Themselves

Even a pet with no symptoms should see a vet once a year, and twice a year once they’re seniors, roughly seven for dogs and ten for cats, or earlier for large breeds. Those visits cover vaccines, parasite prevention, dental checks, weight, and bloodwork that catches problems before symptoms appear. 

For cats especially, the annual visit is often the only time anyone examines them closely.

What to Have Ready When You Call

Having a few key details ready before you call can help your veterinarian understand what’s happening and determine the best next steps. 

• What you’ve noticed, when it started, and how often
• Whether they’re eating, drinking, urinating, and defecating normally
• Any possible exposure: new food, treats, plants, chemicals, other animals
• Current medications and the last vaccine dates
• A short video of the behavior if it’s intermittent, such as a cough or a limp

The more complete the information you can provide, the easier it is for your veterinary team to assess your pet and recommend the right care.

Getting in Touch With Your Veterinarian 

You should get in touch with a veterinarian the moment your pet shows an emergency sign such as breathing trouble, collapse, poisoning, or a blocked bladder; the same day for vomiting, refusing food, sudden pain, or a marked change in behavior; within the week for slow changes like lumps, weight shifts, stiffness, or bad breath; and at least once a year even when everything seems fine. 

With a quarter of dogs and over 40 percent of cats going unseen in a given year, the most common mistake isn’t overreacting; it’s waiting. Trust the instinct that made you pick up the phone, and make the call.
