Episodes of collapse in pets can occur due to many short or long term health conditions or injuries. While some of these issues can potentially be life-threatening, prompt veterinary treatment will maximise the chance of a good outcome for your pet.

Here’s more information about conditions that can cause weakness, fainting, or an inability to walk in dogs and cats.

What are some potential causes of an inability to walk in pets?

Common causes of weakness or a physical inability to walk include:

• Illnesses causing significant dehydration and reduced blood flow, e.g. severe untreated gastroenteritis
• Traumatic incidents causing severe injuries and/or blood loss, such as being hit by a car
• Flare-ups of certain musculoskeletal conditions, such as a prolapsed spinal disc compressing the spine, or severe arthritis
• Toxins such as snake bites or tick paralysis

What are some potential causes of “fainting” in pets?

Altered consciousness or a loss of consciousness in pets can occur secondary to:

• Illnesses causing low blood sugar, such as large intestinal parasite burdens in puppies or kittens
• A neurological event, such as a seizure
• Syncope (fainting due to a lack of blood flow to the brain), which can be caused by heart disease or respiratory disease
• Heatstroke
• Head trauma causing brain swelling
• Episodes of anaphylaxis (a severe allergic reaction), e.g. after a bee sting
• Choking

What should I do if my pet has collapsed or appears unable to walk?

If your pet ever collapses or appears unable to walk, it’s strongly recommended that you seek emergency veterinary assessment. Ideally, phone the veterinary clinic on your way, so that they can prepare for your pet’s arrival.

When moving your pet, it’s safest to gently wrap them in a thick towel or blanket, as even placid pets may lash out if they are in pain or feeling confused.
