Millions of dog owners across the UK are being urged to watch out for the warning signs of liver disease in their pets as experts warn that age-related liver problems can often develop unnoticed.
The liver plays a vital role in a dog’s health, filtering toxins, processing nutrients and producing essential proteins that help keep the body functioning properly. But as dogs get older, the organ can become more vulnerable to disease and decline.
Experts say recognising the early signs of trouble and taking preventative action can make a significant difference to a dog’s quality of life and long-term health.
Five signs your dog may have a liver complaint
According to experts, liver issues in dogs can develop quietly at first, but there are some tell-tale signs owners should look out for:
1. Loss of appetite or weight loss
A sudden disinterest in food may indicate something deeper than fussiness.
2. Lethargy and low energy
If your once-bouncy dog is slowing down more than expected, the liver could be involved.
3. Increased thirst and urination
Excessive drinking or more frequent trips outside can sometimes signal liver dysfunction.
4. Digestive problems
Vomiting, diarrhoea, or pale-coloured stools can point to underlying liver issues.
5. Yellowing of the eyes, gums, or skin (jaundice)
One of the most visible and concerning signs that the liver isn’t working properly.
Jason Layton, founder of natural pet health brand Nature’s Pet, said: “The liver is one of the hardest-working organs in a dog’s body, yet many owners don’t realise there may be a problem until symptoms become quite advanced.
“By understanding the warning signs and supporting liver health proactively, owners can help their dogs stay healthier and more comfortable as they age.”
He added: “If you spot any of these symptoms in your dog, don’t ignore them.
“Always speak to your vet as soon as possible. Liver complaints can worsen quickly if left untreated, but with the right care many dogs can still live full and happy lives.”
Five tips for supporting your dog’s liver health as they age
While not all liver problems can be prevented, there are steps owners can take to give their dogs the best possible chance of maintaining good liver function.
1. Keep weight in check
“Excess weight puts extra pressure on the liver,” said Jason. “Feeding a balanced diet and avoiding too many high-fat treats will help maintain a healthy metabolism.”
2. Limit toxin exposure
“Household chemicals, some garden plants, and even human foods like onions, garlic and chocolate can all damage a dog’s liver. Keep harmful substances well out of reach.”
3. Support with targeted nutrition
“As dogs age, they may need extra nutritional support. A supplement such as LiverEase for Dogs can be useful. It contains liver-friendly ingredients like Milk Thistle, Lecithin, B vitamins and Alpha Lipoic Acid, which work together to help protect liver cells and support detoxification.
“It’s also available in an easy-to-give bacon flavour, so most dogs love it.”
4. Routine check-ups
“Make sure your dog sees the vet regularly for blood tests and health checks. Catching changes early can make all the difference.”
5. Keep them moving
“Exercise not only supports a healthy weight, it boosts circulation and helps every organ, including the liver, to function more efficiently.”
Jason added: “Growing older doesn’t have to mean poorer health. With the right diet, regular exercise, routine veterinary care and appropriate nutritional support, many dogs can enjoy active, happy lives well into their senior years.”
