Puppy emergencies
Puppies have almost no reserves: low blood sugar, dehydration and infection can become life-threatening in hours rather than days. An unvaccinated puppy with vomiting, bloody diarrhoea or sudden lethargy is an emergency until a vet says otherwise. The guides below cover the puppy crises that most often turn serious and how to respond.

When any of these is a go-now emergency
Treat collapse, non-stop vomiting or retching, a swollen hard belly, suspected poisoning, trouble breathing, a seizure lasting more than a few minutes, or heavy bleeding as a call-the-vet-now situation. When in doubt, phone an emergency animal hospital and describe the signs — they will tell you whether to come straight in.
Frequently asked questions
Why are puppy emergencies so urgent?
Puppies have almost no reserves, so low blood sugar, dehydration and infection can become life-threatening within hours. An unwell puppy should be seen sooner than an adult dog.
What are the signs of parvovirus in puppies?
Lethargy, loss of appetite, vomiting and diarrhoea that is often bloody and foul-smelling. An unvaccinated puppy with these signs needs same-day veterinary care.
What do I do if my puppy is weak and wobbly?
If conscious and able to swallow, rub a little honey or glucose syrup on the gums and keep them warm, then call a vet immediately. Give nothing by mouth to a seizing or unconscious puppy.
