One of the hardest parts of pet ownership is deciding whether something is “wait and see” or “go now.” This guide covers general warning signs — but the golden rule comes first: when in doubt, call. A phone call to your vet clinic is free, and staff can help you triage.

Go now: emergency signs

  • Difficulty breathing, choking, or blue/pale gums
  • Collapse, inability to stand, or seizures
  • Suspected poisoning (medications, antifreeze, xylitol, lilies for cats, rodenticide)
  • Severe or uncontrolled bleeding, or major trauma such as being hit by a car — even if they seem fine afterward
  • A bloated, hard belly with retching in dogs (possible bloat/GDV — a true emergency)
  • A male cat straining in the litter box producing little or no urine (possible urinary blockage — life-threatening within hours)
  • Inability to deliver during labor, or heatstroke signs like heavy panting and disorientation

Call today: same-day concerns

  • Repeated vomiting or diarrhea, especially with lethargy or in young/small animals
  • Not eating for 24 hours (sooner for rabbits and small pets — a rabbit that skips meals is always urgent)
  • Sudden limping that doesn’t improve, eye injuries or squinting, or apparent pain
  • Straining to urinate or blood in urine

Book an appointment: worth checking soon

  • Gradual weight loss or gain, increased thirst, changes in appetite
  • New lumps or bumps, persistent scratching, or coat changes
  • Behavior changes: hiding, irritability, house-soiling in a previously trained pet

Know your pet’s normal

The best early-warning system is you. Pets — especially cats, rabbits, and birds — instinctively hide illness. Subtle changes in appetite, energy, litter habits, or sociability are often the first and only clue. A quick daily once-over during petting (checking eyes, coat, and body condition) makes changes obvious early, when treatment works best.

Be ready before you need it

Save these in your phone today: your vet’s number, the nearest 24-hour emergency clinic, and an animal poison control hotline. Emergencies are stressful enough without searching for phone numbers at 2 a.m.
