Lawsuit threatened over Librela
We had just written an article about caring for your dog with arthritis, when this important news came to light in two veterinary journals in one week!!
A lawsuit has been filed against Zoetis regarding safety of its arthritis medication injection Librela. See an article that appeared in the Vet Record here and the article below is from the Vet Times.
Article from Vet Times October 2025
Major pharmaceutical company Zoetis is facing renewed pressure over the safety of some of its osteoarthritis treatments, amid the prospect of fresh legal action and demands for stronger regulatory measures.

Lawyers in the US are preparing to bring a test case against Zoetis, the makers of Librela and its feline equivalent, Solensia, while other actions are also ongoing. But the drugs’ manufacturer has insisted it still has full confidence in the products, despite calls for their withdrawal.

Similar cases

Although the latest action is limited to 25 individual Librela-related claims in California, lead attorney Kirk Hope said he anticipated “hundreds and hundreds” of similar cases could follow. Although other current actions are focused on consumer-related issues, his case alleges both direct harm from use of Librela and that vets were not properly informed of its risks.

He said: “It is our burden for each one of these to show a causal relationship between the drug and the actual damage to them.”

Mr Hope, who expects to file the initial case within days, added that he had been contacted by lawyers in both Australia and Canada in relation to the issue, while there has also been contact with a UK-based campaign group known as Lost and Found Pets in Cambridge and Surrounding Areas (LFPCSA).

‘Full confidence’

But Zoetis said it “continues to have full confidence” in the two products and estimated that around 30 million Librela doses, had been distributed globally between their launch in 2021 and June of this year.

A spokesperson added that no individual symptom or outcome was classified as more frequent than “rare to very rare” under European Medicines Agency standards.

She also insisted case reports “do not confirm causality, and many involve dogs and cats with complex medical histories”.

However, an online petition, signed by more than 1,200 people so far, has called for Librela and Solensia to be withdrawn from sale in the UK until their safety and efficacy can be assured. The Change.org campaign claimed there is “growing concern” both among pet owners and within the veterinary community about adverse events linked to the drugs.

What other options are there?

Omega 3 Daily in dogs and cats

We highly advise the use of pure and natural Omega 3 Daily in both dogs and cats with osteoarthritis and chronic pain. It is the only pet joint supplement to have a higher level of the Omega 3 EPA compared to DHA and fatty acid EPA works at the gene level to mend and repair joints. 

It is fully sustainable and contains Astaxanthin - a  bright pink microalgae with an antioxidant ability that is superior to all others as shown below. It also gives the flavour to fish so makes the oil taste delicious to both dogs and cats!

Astaxanthin has a superior antioxidant effect on joints

We also advise giving cruelty-free Gold Dust Joint and Heart Supplement to your dog or cat in pain

If your dog has ever suffered a cruciate tear or rupture, or you just want to know more about the science behind hyaluronic acid, you might want to read this.

In 2021, researchers ran a study on the effects of oral administration of hyaluronic acid to dogs. They wanted to find out whether giving hyaluronic acid orally (rather than by injection) would really make any difference to dogs who’d had surgery for cranial cruciate ligament (CCL) injury.

The researchers knew that long chain hyaluronic acid could be a very effective treatment when injected. But at that point, there was scarce scientific evidence for administering it orally.

So they gathered 55 dogs who’d had cruciate surgery, half were given long- chain hyaluronic acid orally every day for 10 weeks (the other half were given placebo).

At the end of this time they analysed the chemistry of the joint fluid and here’s what they found: “Post-op oral HA administration in canine patients with Cranial Cruciate Ligament injury leads to improvements in osteoarthritis biomarkers, namely higher synovial fluid HA concentrations and reduced synovial fluid paraoxonase-1 concentrations. These findings support the bioavailability of orally-administered HA and its usefulness in improving biomarkers of osteoarthritis.” 

Serra Aguado CI, Ramos-Plá JJ, Soler C, Segarra S, Moratalla V, Redondo JI. Effects of Oral Hyaluronic Acid Administration in Dogs Following Tibial Tuberosity Advancement Surgery for Cranial Cruciate Ligament Injury. Animals (Basel). 2021 Apr 27;11(5):1264. doi: 10.3390/ani11051264. PMID: 33925642; PMCID: PMC8146498.

In simple terms, for the first time, this study showed that oral hyaluronic acid can change what's happening inside dog’s joints - without the need for nasty injections. 

The dogs that took oral hyaluronic acid had significantly higher levels of hyaluronic acid in their joint fluid - meaning better lubrication. But they also had lower levels of an inflammatory marker called PON-1.

This suggests reduced inflammation, even after major stifle surgery. Oral hyaluronic acid supported recovery and improved the biological environment without a single injection.

So whether your dog is recovering from surgery, resting after an injury, or suffering with other joint issues - you can be assured that there’s science behind Zooomy.

Zooomy is formulated using long-chain hyaluronic acid - and that’s not what you find in most pet supplements. Other joint supplements typically use short chain HA (which isn’t proven to do anything).

At Zooomy, they use the only kind of hyaluronic acid proven to be absorbed and helpful in dogs. Because they want it to work.  If you’d like to see the effects for yourself, order your dog their Zooomy now.
