Can cats and dogs catch colds?
Have you ever wondered whether cats and dogs can catch colds? It’s that time of year where more and more of us are catching colds. If you notice your dog or cat sneezing, you may suspect that they have caught the flu too.
Can dogs and cats catch human colds?
No human cold or virus has been shown to be transmissible to dogs or cats. Likewise, dog and cat viruses are not transmissible to humans.
Just like us, however, cats can catch colds (also known as feline upper respiratory disease) – but can dogs get colds? Canine influenza or dog flu is much less common. It’s a virus that causes similar symptoms as a human flu and is very rare in the UK.
Dog flu or canine influenza
Dogs very rarely get the flu. If your dog is sneezing or has the sniffles, it may be due to a number of things, including allergies, kennel cough, foreign bodies or other causes of respiratory tract inflammation, but it is very unlikely to be dog flu. So far, only a couple of cases of canine influenza have been identified in the UK – it’s more common in the US.
Kennel cough is far more common than canine influenza and can also present with sneezing and coughing. It is highly contagious and can be caused by a mix of viruses and bacteria, most commonly Parainfluenza (a virus) and Bordetella Bronchiseptica (a bacteria).
Kennel cough usually resolves itself without treatment, but if it persists your vet may suggest treatment to manage the symptoms. There is also a vaccine available for kennel cough.
If you do notice your dog is showing any of the following signs, sneezing, nasal discharge, coughing, difficulty breathing, listlessness or loss of appetite, contact your vet for advice.
Cat colds or cat flu
Cat flu is much more common than dog flu. Although cats do catch colds, it isn’t the same common cold virus that us humans catch. Cat flu, however, does give cats the same side effects as us. So, if your cat is sneezing and coughing or has a fever or loss of appetite, it may well be suffering from cat flu.
Treatment and recovery
There is no cure for cat flu but there are some things you can do to relieve symptoms for your cat. For example, wipe your cat’s eyes with a clean cloth soaked in salt water. This can help remove any discharge from the nose or eyes. Similarly, give your cat access to a comfy bed and lots of fresh water from a clean bowl.
As with humans, the flu can cause a loss of appetite for cats. This is because your cat may have a blocked nose and will not be able to smell food as well. If your cat’s reluctant to eat, give them their favourite food (chicken or fish) and warm it up, as this will heighten the aromas.
Your vet can help you to manage the symptoms of cat flu, making sure your cat is as comfortable as possible.
Once infected, cat flu is a lifelong condition and will usually flare up at times of stress.
The best way to prevent your cat from getting the flu is to get them vaccinated. Cats can have a yearly vaccination from nine weeks old, so speak to your vet about this. If your cat has already had the flu, the vaccine will not work.
When to see the vet
Cat flu can be fatal in kittens and older cats – and is usually more common due to their weaker immune systems. If your cat has a pre-existing heart or lung condition, speak to your vet about treatments for the flu.
