A dog, cat or rabbit that suddenly collapses or cannot be woken: what should you do? This article reorganises veterinary encyclopedia material by species for triage, covering rabbits / guinea pigs / chinchillas, dogs and cats, with the encyclopedia source marked for each entry (9 anchors). Identify the species first, then read the red flags and what you can do.

A dog, cat or rabbit that suddenly collapses or cannot be woken: what should you do?

First confirm which species you are dealing with. The same sign is handled differently in different species, and copying what is done for another species can be harmful. This article covers: rabbits / guinea pigs / chinchillas, dogs, cats.

Applies to all species

Signs: body temperature too low, limpness, slow response to stimulation

  • Warm the animal passively with a blanket, keep direct high-heat sources from touching the skin directly (risk of burns), and get it to a veterinarian immediately

Signs: applies to almost all species; cats and donkeys tolerate fasting particularly poorly (fasting in cats rapidly triggers hepatic lipidosis; fasting in donkeys can trigger hyperlipidaemia), so in these two, the moment they stop eating should be treated as the start of an emergency

  • ❗ [All species] No direct handling source was found for this species at this level. Do not apply what is done for other species; contact a veterinarian familiar with this species immediately.

Signs: applies to almost all species

  • ❗ [All species] No direct handling source was found for this species at this level. Do not apply what is done for other species; contact a veterinarian familiar with this species immediately.

Signs: newborn puppies, kittens and other neonates, toy-breed dogs, elderly animals, animals in shock

  • ❗ [All species] No direct handling source was found for this species at this level. Do not apply what is done for other species; contact a veterinarian familiar with this species immediately.

Rabbits / guinea pigs / chinchillas

Signs: dehydration from acute watery diarrhoea; a stuporous state in which the animal cannot be woken (normal hibernation-like torpor must be ruled out first before judging).

  • ❗ [Rabbits / guinea pigs / chinchillas] No direct handling source was found for this species at this level. Do not apply what is done for other species; contact a veterinarian familiar with this species immediately.

Signs: sudden hind-limb weakness or seizures (suspected hypoglycaemia), persistent vomiting with inability to eat, severe difficulty breathing, severe abdominal swelling and pain.

  • ❗ [Rabbits / guinea pigs / chinchillas] No direct handling source was found for this species at this level. Do not apply what is done for other species; contact a veterinarian familiar with this species immediately.

Dogs

Signs: canine parvovirus (CPV), hypoglycaemia, intussusception

Signs: triggers insulin release → acute hypoglycaemia; can also lead to liver failure

Cats

Signs: shock, anaemia, methaemoglobinaemia

This article reorganises veterinary encyclopedia material by species for triage, with the source marked entry by entry (9 anchors in total; see the evidence chain). The sources at the end are the authoritative material cited by the chapters covered here; the correspondence is at chapter level and does not mean that every sentence traces back to that particular source.

Sources are marked entry by entry from the encyclopedia material (see the evidence chain at the end); it has not been clinically reviewed by a named veterinarian.
