Dog Health Symptoms: When to Call Your Vet

6-minute read · Reviewed against the Loyal Saints nutrition standard

Quick answer

Call your veterinarian promptly if your dog shows repeated vomiting or diarrhea (especially with blood), refuses food for more than 24 hours, has difficulty breathing, a distended or painful abdomen, sudden lethargy or collapse, signs of pain, or any sudden behavioral change. When in doubt, it's always safer to call — many serious conditions are far more treatable when caught early.

Dogs are instinctively good at hiding illness, so knowing which signs warrant veterinary attention is one of the most important parts of being a dog parent. This is general guidance — you know your dog best, and when something feels wrong, it's always reasonable to call.

Call right away (urgent)

  • Difficulty breathing, choking, or collapse
  • A distended, bloated, or hard painful abdomen (can signal bloat — an emergency)
  • Repeated vomiting or diarrhea, especially with blood
  • Inability to urinate or defecate, or straining
  • Suspected poisoning or ingestion of a toxic substance
  • Seizures, sudden weakness, or loss of coordination

Call soon (within a day or two)

  • Refusing food for more than 24 hours
  • Persistent lethargy or marked behavior change
  • Chronic itching, ear infections, or skin issues
  • Ongoing soft stool or digestive trouble beyond a few days
  • Noticeable weight loss or gain

Nutrition-related signs worth discussing with your vet

Chronic loose stool or gas

Often diet-related; worth discussing food quality and ingredients with your vet.

Itchy skin, paws, or recurrent ear infections

Frequently linked to food sensitivities — a candidate for a vet-guided elimination diet.

Dull coat or excessive shedding

Can reflect inadequate protein or omega-3s; diet quality matters.

Low energy or unexplained weight change

Always worth a veterinary conversation that includes diet.

Good nutrition supports overall health, but it never replaces veterinary care. Many of the chronic, low-grade issues dog parents notice — digestive trouble, itchy skin, dull coats — do have a dietary component worth discussing, which is exactly why we built Loyal Saints around clean, whole-food nutrition. But acute or worrying symptoms always belong with your veterinarian first.

Frequently Asked Questions

When should I take my dog to the vet for vomiting or diarrhea?

Call promptly if vomiting or diarrhea is repeated, contains blood, or is accompanied by lethargy, a painful abdomen, or refusal to eat. A single isolated episode in an otherwise bright, active dog can sometimes be monitored briefly, but when in doubt, call your vet — these symptoms can signal serious conditions.

How long can a dog go without eating before I worry?

If a healthy adult dog refuses food for more than 24 hours, contact your veterinarian — especially if accompanied by lethargy, vomiting, or other symptoms. Puppies, seniors, and dogs with health conditions warrant faster attention. Appetite loss is a common early sign of many illnesses.

What are signs of a food allergy in dogs that need a vet?

Chronic itching (especially paws, ears, face), recurrent ear infections, persistent loose stool, and skin irritation can indicate food sensitivities. A veterinarian can guide a proper elimination diet to identify the trigger and rule out other causes. Loyal Saints single-protein formulas are well-suited to vet-guided elimination diets.

Can diet cause my dog's symptoms?

Some chronic, low-grade symptoms — soft stool, gas, itchy skin, dull coat — often have a dietary component, and improving food quality can help. However, symptoms should always be evaluated by a veterinarian first, since many conditions share these signs. Diet is supportive, not a diagnosis or treatment.
