Pet owners have been warned about the danger of antifreeze to dogs.
Dogs Trust Newbury has issued the alert as temperatures drop and the winter weather sets in.
Antifreeze, commonly found in de-icing products, screen wash, and car engines, contains ethylene glycol, a highly toxic substance.
If ingested, it can cause severe illness or even death, even in small amounts.
The substance has a sweet taste, making it appealing to animals.
Unfortunately, it can cause acute, irreversible kidney failure and neurological issues in dogs.
Signs of poisoning may not appear immediately.
Owners are advised to watch for symptoms such as vomiting, lethargy, unsteady behaviour, increased thirst and urination, rapid breathing, and seizures.
If any of these symptoms are present, immediate veterinary care is needed.
Dogs Trust Newbury said: "Prompt treatment is critical to prevent irreversible damage and if left untreated, ingestion of antifreeze can lead to kidney failure, coma, and death.
"The faster treatment begins, the better the chances for a full recovery."
Charlie Dobson, senior veterinary surgeon at Dogs Trust, said: "Antifreeze is extremely dangerous for dogs, and other pets, because even a small amount can lead to serious, often fatal, health issues.
"Unfortunately, because it has a sweet taste it can be particularly enticing to pets.
"The best way to protect your dog is to keep all antifreeze and de-icing products securely stored, avoid using them around your dog, and seek veterinary care immediately if you suspect they’ve ingested any."
Antifreeze is not the only risk facing dogs and their owners in this weather.
Dogs Trust has published some easy-to-follow guidance to ensure dogs remain healthy and happy.
Firstly, owners are advised to keep their dogs warm.
Some breeds grow thick furry coats all year round, so as the weather gets colder, consider letting your dog's fur grow longer.
Some shorter-haired pooches and puppies may need a little bit of help staying warm, so consider buying them a sensible winter coat.
Snow can be disorientating for dogs, and they can become easily lost in it.
Make sure your dog is wearing a collar and ID tag, and their microchip details are up to date.
After walks, ensure you wipe your dog’s legs, feet, and stomach as grit from the roads and dampness from rain or snow can irritate their skin.
Owners are advised to avoid letting their dogs walk on frozen water bodies as the ice may not be thick enough to take the dog's weight.
Lastly, indoor games and enrichment activities are suggested to keep dogs entertained and mentally stimulated throughout the cold season.
