We didn’t set out to become herbalists. We set out to help one small, stubborn, impossibly loveable Corgi named Maude. But in researching what her body needed — really needed — we kept coming back to one organ that doesn’t get nearly enough attention: the liver.
The liver is quietly one of the hardest-working organs in your dog’s body. It filters toxins, processes medications, supports digestion, and helps regulate hormones. When it starts to struggle, the signs can be easy to miss — until they’re not.
This post is for every dog owner who’s noticed something’s a bit off with their dog and isn’t sure where to look.
What Does the Liver Actually Do for Your Dog?
Before we talk about signs, it helps to understand what the liver is dealing with on a daily basis.
Your dog’s liver is processing everything that enters their body — food, water, medications, flea treatments, lawn chemicals tracked in on paws, and the questionable things they sniff out on walks. It converts nutrients into usable forms, filters waste from the blood, produces bile for fat digestion, and stores vitamins and energy.
It’s remarkable, really. And like any hardworking system, it can get overwhelmed.
7 Signs Your Dog’s Liver Might Need Support
1. Yellowing of the Eyes, Gums, or Skin (Jaundice)
This one’s the most visible. If you notice a yellow tinge to your dog’s eyes, gums, or skin — especially around the ears or belly — it can indicate that bilirubin (a waste product processed by the liver) is building up in the bloodstream. This warrants a vet visit promptly
2. Unexplained Weight Loss or Loss of Appetite.
A dog who suddenly goes off their food or starts dropping weight without a clear reason
may be experiencing liver stress. The liver plays a direct role in nutrient metabolism — when it’s not working efficiently, appetite and body condition often suffer.
3. Excessive Thirst and Urination
Increased drinking and urination are one of those symptoms that can point to several things, but liver dysfunction is high on the list. If your dog seems to be at the water bowl constantly, it’s worth getting checked out.
4. Vomiting or Diarrhea
Occasional digestive upset is normal for dogs (they are opportunistic eaters). But persistent vomiting or loose stools without an obvious cause can be a sign the liver isn’t properly processing toxins or producing adequate bile for digestion.
5. Lethargy and General Dullness
This is the one that often first catches an owner’s eye. A dog who used to bound to the door now barely lifts their head. Low energy, a dull coat, and a general “not quite themselves” quality can all be associated with a liver that’s under pressure.
6. Swollen Abdomen
Fluid accumulation in the abdomen (called ascites) can occur in more advanced liver conditions. If your dog’s belly looks distended or feels firm, see your vet.
7. Behavioural Changes or Disorientation
In some cases, toxins that the liver isn’t adequately filtering can affect brain function — a condition called hepatic encephalopathy. Signs include confusion, circling, staring into space, or unusual behavioural shifts. This is a more serious indicator and needs veterinary attention.
Dogs Who May Be More at Risk
While any dog can experience liver stress, certain factors can increase the likelihood:
Older dogs — liver function naturally declines with age
Dogs on long-term medications — many pharmaceuticals are processed through the liver. Dogs exposed to garden chemicals or pesticides — even if they’re not directly treated
Certain breeds — Bedlington Terriers, Dobermans, Labradors, and West Highland White Terriers
Terriers have known genetic predispositions to liver conditions
Dogs who’ve had repeated vaccinations or flea/tick treatments in close succession
What to Do If You Suspect Liver Issues
First: see your vet. A simple blood panel can check liver enzyme levels (ALT, AST, ALP, and GGT are the key markers) and give you a real picture of what’s happening. Don’t wait on a hunch if your dog is showing multiple signs.
Second: look at what they’re being exposed to. Are they on a particularly processed kibble? Are they getting regular chemical flea or tick treatments? Are you using lawn sprays?
These all add to the liver’s toxic load.
Third: consider gentler, supportive choices wherever possible. This doesn’t mean abandoning conventional care — it means complementing it. Many dog owners look to botanical herbs traditionally used for liver support as part of a broader wellness routine.
Traditional Herbs Used for Liver Support in Dogs
These are some of the most well-regarded botanicals in herbal medicine for supporting healthy liver function. They’ve been used in both human and veterinary contexts for centuries:
Milk Thistle (Silybum marianum) is probably the most widely studied herb in relation to liver health. Its active compound, silymarin, is thought to support liver cell regeneration and act as an antioxidant.
Dandelion Root (Taraxacum officinale) A gentle, traditional liver and digestive tonic. Dandelion root has a long history of use for supporting bile flow and mild liver detoxification.
Schisandra Berry (Schisandra chinensis) Used in traditional Chinese medicine for centuries, schisandra is known as an adaptogen and is traditionally associated with liver-protective properties.
Artichoke Leaf (Cynara scolymus) A lesser-known but respected botanical for supporting bile production and liver function, with a tradition of use stretching back to ancient Egypt.Always discuss herbal supplements with your vet before starting, particularly if your dog is on existing medication.
A Note from Us
When Maude’s health journey began, we were overwhelmed by how little clear information was out there for dog owners who wanted natural options — and how hard it was to find products made with care, transparency, and real ingredients.
That’s why everything we make at Herb & Hound Co. is produced in small batches here in New Zealand, using certified organic herbs and a glycerine base that’s alcohol-free and gentle enough for sensitive systems. We believe dog owners deserve to know exactly what they’re giving their animals — and why.
If you’re curious about liver health for your dog, we’d encourage you to start with a vet conversation and explore your options with open eyes.
