Solensia is a feline-only medication, so there is no Solensia for dogs. The canine equivalent is bedinvetmab, a monthly injection that targets nerve growth factor to relieve osteoarthritis pain in dogs. Both drugs work the same way, but they are approved for different species and cannot be swapped.

Quick Answer

Solensia (frunevetmab) is approved only for cats. It is not labeled or dosed for dogs.
The dog equivalent is bedinvetmab, sold under the brand name Librela in the United States.
Bedinvetmab is a once-monthly subcutaneous injection given by your veterinarian.
It is used for osteoarthritis pain, not for acute injuries, postoperative pain, or neurologic conditions.
Your veterinarian decides whether your dog is a candidate after an exam, bloodwork, and a pain assessment.

What Is Solensia for Dogs?

There is no such product. Solensia is the brand name for frunevetmab, a monoclonal antibody approved for cats with osteoarthritis pain. Dogs and cats have different nerve growth factor biology, different antibody clearance, and different approved dosing. Giving a cat product to a dog is not appropriate and is not supported by any label or safety data.

The canine equivalent is bedinvetmab, marketed as Librela. It is the same class of drug (an anti-nerve growth factor monoclonal antibody) but it is formulated and dosed for dogs. If you have heard people talk about a "Solensia shot for dogs," they are almost certainly referring to bedinvetmab.

How Does the Solensia Equivalent for Dogs Work?

Nerve growth factor (NGF) is a protein the body releases when joints are damaged or inflamed. NGF binds to receptors on pain-sensing nerves and turns up the volume on osteoarthritis pain. Monoclonal antibodies like bedinvetmab bind NGF directly and stop it from activating those nerves.

This is a targeted approach. It does not act like a nonsteroidal anti-inflammatory drug (NSAID), which blocks prostaglandins throughout the body. It does not act like an opioid, which changes pain perception in the brain and spinal cord. Because the target is specific, bedinvetmab is often used in dogs that cannot tolerate NSAIDs or that need additional pain control.

Pain management in veterinary medicine is usually multimodal, meaning several drugs and techniques are combined. Regional nerve blocks, for example, are used to reduce perioperative opioid needs in dogs undergoing spinal surgery [1]. Other approaches, including cannabidiol, have been studied as adjuncts for canine osteoarthritis, with variable results and mild side effects such as gastrointestinal upset and sedation reported in dogs and cats [2]. Bedinvetmab fits into this broader picture as one option, not the only option.

Solensia Injection for Dogs: Dosing Basics

Who decides the dose?

Your veterinarian does. The dose is calculated from your dog's body weight and overall health. Never use a dose intended for a cat, and never split or adjust a dose on your own.

How is it given?

Bedinvetmab is given as a subcutaneous injection, which means under the skin. In most cases, your veterinarian or a trained technician administers it in the clinic. It is typically given once a month.

What if you miss a dose?

Call your veterinary clinic. They will tell you when to reschedule. Do not double up to make up for a missed injection. If your dog misses a monthly dose, pain control may fade before the next one is due, so let your veterinarian know how your dog is doing.

How long until it works?

Some dogs improve within days, others take a few weeks. Response varies. Your veterinarian will likely ask you to track mobility, willingness to walk, stiffness after rest, and activity level so the effect can be judged over time. Validated owner questionnaires such as the Canine Brief Pain Inventory are used in research and practice to score osteoarthritis pain consistently [3].

Solensia for Dogs Side Effects

Most dogs tolerate bedinvetmab well. Still, any injectable monoclonal antibody can cause reactions, and some are serious. The table below covers what owners most often ask about.

Side effect	How common or serious	What to do
Injection site reaction (swelling, pain, redness)	Uncommon, usually mild	Note it and tell your veterinarian at the next visit. Call if it worsens or your dog keeps licking the area.
Vomiting or diarrhea	Uncommon, usually mild	Withhold food briefly if advised, keep water available, and call your veterinarian if it lasts more than a day.
Lethargy or reduced appetite	Uncommon	Monitor for 24 to 48 hours. Call if your dog stops eating or seems painful.
Itching, hives, facial swelling	Rare but urgent	This can signal an allergic reaction. Call your veterinarian right away or go to an emergency clinic.
Difficulty breathing, collapse	Rare and life-threatening	Emergency. Go to the nearest veterinary emergency hospital now.
Worsening lameness or new neurologic signs	Uncommon	Needs same-day veterinary assessment.

General pain management research in dogs shows that side effects and rescue analgesia needs vary by procedure, drug combination, and individual patient [4]. The same principle applies here. Your dog's response is individual, and monitoring matters more than any general statistic.

If your dog shows neurologic signs such as wobbling, knuckling, or weakness, your veterinarian may perform a structured neurologic examination to localize the problem Neurological Examination in Dogs: A Practical Guide. Lameness that does not improve may also need an orthopedic workup to rule out problems beyond osteoarthritis Orthopedic Examination and Lameness Localization in Dogs.

Who Should Not Take It and Drug Interactions

Bedinvetmab is not right for every dog. Your veterinarian will review the following before prescribing.

Dogs with known hypersensitivity to the drug or its ingredients.
Dogs with active infection, fever, or illness. Wait until your dog is stable.
Dogs with certain neurologic conditions. NGF-targeting drugs have been associated with neurologic side effects in some patients, so a full neurologic exam matters.
Pregnant, breeding, or lactating dogs. Safety has not been established in these groups.
Dogs under the labeled minimum age. Follow your veterinarian's guidance.

Interactions with other drugs are not fully mapped. In practice, bedinvetmab is often combined with NSAIDs, gabapentin, amantadine, or other pain medications. Your veterinarian will weigh the benefits and risks of each combination. Do not start or stop any medication without asking first.

If your dog is on multiple drugs, keep a written list, including supplements. Bring it to every visit. This is the same discipline that keeps parasite preventives safe, whether you use a chewable like Nexgard For Dogs or a topical product.

Overdose and When to Call for Help

An overdose of bedinvetmab is unlikely at home because it is given in the clinic. If you think your dog received too much, call your veterinarian or a pet poison control hotline immediately. Do not wait for symptoms.

Signs that need urgent attention after any injection include vomiting that will not stop, severe lethargy, trouble breathing, swelling of the face or throat, or collapse. These can indicate a serious reaction.

If your dog develops sudden weakness, inability to walk, or loss of pain sensation in a limb, this is an emergency. Some neurologic conditions in dogs, such as ischemic neuromyopathy, can cause limb weakness and are associated with survival outcomes that depend on how quickly they are recognized and treated [5]. Do not assume a new weakness is just arthritis.

Cost of the Solensia Equivalent for Dogs

Cost varies widely by clinic, region, dog size, and whether the injection is bundled with an exam. Because the drug is weight-based, a large dog costs more per dose than a small dog. Your clinic can give you an exact price for your dog.

Ask about the following when you call for a quote.

The injection itself
The office visit or recheck exam
Any bloodwork your veterinarian wants before starting
Whether the clinic offers a monthly plan or package

Many owners find that the monthly injection is easier to give than daily pills, especially for dogs that resist oral medication. That convenience is part of the appeal, but it does not replace regular veterinary monitoring.

Solensia for Dogs Arthritis: What to Expect

Osteoarthritis is a chronic, progressive disease. No drug reverses joint damage. The goal is to reduce pain, improve mobility, and maintain quality of life.

Bedinvetmab can help with pain, but it works best alongside other measures.

Weight management. Extra pounds load painful joints.
Controlled exercise. Short, frequent walks often beat long, hard sessions.
Joint-friendly surfaces. Rugs and ramps help dogs with slippery floors and stairs.
Physical rehabilitation. Therapists can design a safe strengthening plan.
Other pain medications. Your veterinarian may combine drugs for better control.

Track your dog's good days and bad days. Bring notes to recheck visits. Pain scoring tools help veterinarians compare visits objectively, and owner-reported quality of life is part of that picture [3]. If your dog's pain is not controlled after a fair trial, ask about adjusting the plan.

Limitations and When to Contact a Veterinarian

This article cannot tell you whether your dog should receive bedinvetmab. That decision needs a veterinarian who has examined your dog, reviewed bloodwork, and considered other conditions. Individual cases always need professional assessment.

Contact your veterinarian the same day if you notice:

Vomiting or diarrhea lasting more than 24 hours
Refusing food for more than a day
Marked lethargy or weakness
Swelling, redness, or pain at the injection site that is getting worse
Increased lameness or stiffness after the injection

Go to an emergency clinic now if you see:

Difficulty breathing, wheezing, or noisy breathing
Facial swelling, hives, or widespread itching
Collapse, unresponsiveness, or seizures
Sudden inability to walk or stand
Severe pain that does not respond to prescribed medication

Schedule a routine visit if:

Your dog's mobility is slowly declining
You are unsure whether the monthly injection is still helping
You want to discuss adding or changing pain medications
Your dog has new symptoms between injections

If your dog has vomiting, diarrhea, and lethargy together, especially with bloody stool, your veterinarian may also consider infectious causes such as parvovirus Parvo In Dogs. Rapid testing and supportive care save lives.

Frequently Asked Questions

Can I give my dog Solensia?

No. Solensia is approved for cats only. Dogs need a canine-specific product, and your veterinarian can determine whether bedinvetmab is appropriate.

Is bedinvetmab the same as Solensia?

They belong to the same drug class and both target nerve growth factor, but they are different products made for different species. They are not interchangeable.

How often is the injection given?

It is typically given once a month by your veterinarian. The exact schedule depends on your dog's response and your clinic's protocol.

Can my dog take bedinvetmab with other pain medications?

Often yes, but the combination must be chosen by your veterinarian. Some drugs interact or add side effects, so never add or remove a medication on your own.

Does the injection cure arthritis?

No. Osteoarthritis is progressive and cannot be cured. The injection reduces pain and can improve comfort and mobility, and it works best with weight control, exercise management, and other treatments.

What if my dog seems worse after the injection?

Call your veterinarian. Some dogs have a temporary reaction, and some have unrelated problems that need attention. Worsening weakness or lameness should be evaluated promptly.
