Canine health is two decades behind.
We're closing the gap.

Hormone decline in dogs often shows up as stiffness or slower recovery after activity, weight gain or a slower metabolism even without diet changes, subtle behavioral or mood shifts, and reduced energy or enthusiasm for exercise. Because hormones regulate multiple systems at once, these changes tend to appear gradually and across more than one area rather than as a single obvious symptom. If you notice several of these changes together, it's worth mentioning to your veterinarian, since some can overlap with other health conditions.

Elk velvet antler provides bioactive compounds like growth factors and collagen peptides, but those compounds need cofactors to be used effectively by the body. Elk liver supplies exactly that: concentrated, bioavailable vitamin A, B12, heme iron, and zinc. Used together, the bioactive layer and the nutritional layer support each other. Antler alone provides signaling compounds without enough raw material to act on, and liver alone provides nutrients without the compounds to direct their use.

Spaying or neutering removes the ovaries or testes, the body's main source of sex hormones like estrogen and testosterone. Once removed, circulating levels of these hormones drop sharply and permanently, since the adrenal glands only produce them in much smaller amounts. This shift affects far more than reproduction. Hormones act as signaling molecules throughout the body, so the change influences muscle maintenance, metabolism, joint and coat health, mood, and cognitive function too.

Whole-food nutrient sources like elk liver often provide better absorption than synthetic or isolated vitamins, since nutrients occur in their natural forms alongside the cofactors the body uses to process them. Heme iron from animal sources, for example, is absorbed significantly more efficiently than the non-heme iron found in most synthetic supplements. This is why Hans uses elk liver as a whole-food nutritional source rather than a synthetic vitamin blend.

Yes, hormone levels decline gradually with age in every dog, whether or not they've been spayed or neutered, since natural hormone production slows as part of normal aging. The decline tends to be more gradual in intact dogs than the sharper drop that follows spay or neuter surgery, but the same systems, metabolism, joints, energy, and mood, are affected over time. Talk to your veterinarian about whether hormone support fits your dog's specific life stage and health history.

Hormone replacement means directly administering synthetic or bioidentical hormones, a medical intervention that requires veterinary oversight and prescription. Hormone support works differently, providing nutritional and bioactive compounds, like the growth factors and cofactors in elk velvet antler and elk liver, that give the body's existing systems more of what they need to function well. Hans is formulated as a daily hormone support chew, not a hormone replacement therapy. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

The biological mechanism behind hormone decline, the loss of ovarian or testicular hormone production, is the same across all dogs, but its visible effects can differ by breed and size. Larger breeds tend to show joint and mobility changes earlier because of their size and weight bearing joints, while smaller breeds may show metabolic or coat changes first. Age at spay or neuter, activity level, and genetics also play a role in how and when decline becomes noticeable.

No, unlike synthetic hormone therapy, which can signal the body to reduce its own hormone production through natural feedback loops, nutritional and bioactive support does not introduce external hormones for the body to react to. Elk velvet antler and elk liver work by supplying growth factors and nutritional cofactors that support the body's existing processes, rather than replacing or overriding them. This is one of the key distinctions between hormone support and hormone replacement therapy.

Yes, a peer-reviewed study published in the Canadian Veterinary Journal found that dogs given daily elk velvet antler supplementation showed measurable improvements in gait, daily activity, and overall vitality, with no adverse effects across a full panel of blood tests. The dogs in the study had osteoarthritis, and researchers used force plate gait analysis and veterinary assessment to track results (Moreau et al., 2004;45(2):133-139, PMID 15025149). Hans uses this same ingredient, elk velvet antler, as the bioactive core of its daily formula.

Many owners choose to start hormone support within the first year after spay or neuter, since hormonal decline is gradual and cumulative rather than immediate. Small early changes can compound into more noticeable effects on metabolism, coat, joints, and energy by middle age, so starting earlier gives support more time to work. Talk to your veterinarian about the right timing for your dog's individual health needs.

Elk velvet antler naturally contains growth factors including IGF-1 (insulin-like growth factor 1) and TGF-B (transforming growth factor beta), along with collagen peptides, glucosamine, chondroitin sulfate, and amino acids. IGF-1 plays a role in cell growth, tissue repair, and metabolism, while TGF-B is involved in maintaining connective tissue. These compounds occur naturally because antler velvet is one of the fastest regenerating tissues in the mammalian world, rebuilding an entire vascularized structure every year.

Yes, the peer-reviewed study on elk velvet antler in dogs monitored complete blood panels throughout the trial and found no adverse effects on any blood markers tested. The ingredient also has a long history of use in traditional and veterinary contexts without reports of significant toxicity. As with any supplement, dogs with existing health conditions or those on other medications should check with a veterinarian before starting something new.
