Pet Costs

ACL surgery on a dog cost calculator

Work out what cruciate surgery for a dog will cost from the technique, the surgeon's fee, and the recovery that follows. The number a clinic quotes on the phone is usually the procedure itself, and the repair is a course that runs for months: imaging to confirm the tear, the operation, recheck visits, and rehab that decides whether the knee holds. Two things move the total more than anything else: which technique your dog's size and activity call for, and whether the second knee follows the first. The calculator adds it up.

§ 01 Your numbers

Change anything. The answer updates as you type.

The visit where the tear is found: a hands-on knee exam, often with sedation so the joint can be tested properly. A referral appointment with a surgeon may be more than a general practice visit.
Radiographs to confirm the tear, measure the joint angles the surgery is planned around, and rule out the other things that make a dog limp. Sedation is usually part of the charge.
The operation itself: surgeon, anaesthesia, implants, and the theatre time. This is the line that swings most, because a bone-cutting repair at a specialist and a suture-based repair at a general practice are different operations at different prices. Ask which one you are quoted.
How many stifles you are budgeting for. The cruciate that has not torn yet is a live question in a dog that has torn one, so ask your surgeon what the risk looks like for your dog before you assume the answer is one.
Pain relief, anti-inflammatories, and any sedative for a dog that will not stay quiet. A course total for the weeks after surgery, not a per-visit charge.
The follow-ups that confirm the bone is healing and the implants are where they should be. A bone-cutting repair is usually re-imaged before the dog is released back to normal activity.
Structured rehab over the months of recovery: controlled exercise, and at some practices underwater treadmill work. Often quoted as optional, and often the line that decides how well the leg works a year later.

$2,500 to $6,000 is a bone-cutting repair at a specialist on one knee, with rechecks and structured rehab included. Ask whether the post-op X-rays are in the fee.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

THE TECHNIQUE IS THE PRICE. ASK WHICH ONE YOU ARE BEING QUOTED.
A dog's cranial cruciate ligament does not usually snap the way a footballer's does; it frays and gives way, and the repair is not a repair of the ligament at all. The suture-based approach runs a strong line outside the joint to do the ligament's job while scar tissue builds, and it is the cheaper operation, generally offered for smaller and less active dogs. The bone-cutting approaches change the geometry of the top of the shin so the joint no longer needs the ligament, which is a bigger operation with implants, a specialist, and a fee to match. They are quoted as if they were the same item on a menu, and they are not. Ask your surgeon which technique they propose for your dog's size and activity, and why, before you compare a quote with anyone else's.

The knee that has not torn is the sleeper cost. A dog that ruptures one cruciate has a real chance of going through the other, often within a year or two, because whatever loaded the first knee is usually still there: the conformation, the weight, the way the dog moves. That is not a certainty and it is worth asking your own surgeon about your own dog, but it is common enough that budgeting for one knee and then being handed a second surgery is an expensive way to find out. The knees input above exists for that reason.

Rehab is quoted as optional and behaves like part of the operation. The surgery gives the joint a chance; the months of controlled activity that follow are what turn it into a working leg. Skipping the structured part is a real choice some owners make for real reasons, but it is a choice about the outcome rather than a discount on the same outcome. Ask what the practice's own release protocol looks like and what it costs before you strike the line.

Waiting is not a free option, though it is sometimes the right one. A knee that is unstable gets arthritic, and a dog that will not use one back leg loads the other harder. Some dogs, particularly small ones, do settle with management rather than surgery. Both of those are conversations for your vet about your dog, not a rule, and the cost of the second path is a long tail of medication and rechecks rather than one bill.

The defaults are ours and are a starting point. The exam, imaging, surgeon's fee, and rehab are yours, and the estimate turns most on which technique you are quoted and whether one knee or two ends up being repaired.

Frequently asked questions

How much does ACL surgery on a dog cost?
It depends far more on the technique than on the dog. A suture-based repair outside the joint at a general practice and a bone-cutting repair with implants at a specialist are different operations at different prices, and both get called ACL surgery. On top of the surgeon's fee you are paying for the exam and sedated X-rays that confirmed the tear, the meds and rechecks afterwards, and the rehab through the months of recovery. The calculator above builds the total from your own quote.
Why is the quote I got so different from the one someone else got?
Usually because it is a different operation. Ask which technique is proposed, whether the fee includes anaesthesia, implants, and the post-op X-rays, and what the practice charges for the rechecks. A specialist bone-cutting repair on a large active dog and a suture repair on a small one are not comparable numbers, and neither is a quote that includes rehab against one that does not. Get both quotes itemised and the gap usually explains itself.
Will my dog need the other knee done too?
It is a real risk rather than a certainty. A dog that tears one cruciate often has the same underlying loading on the other side, and second ruptures within a year or two are common enough that surgeons raise it unprompted. Ask yours what the odds look like for your dog's build, weight, and activity. If the answer is that it is likely, budget for two knees now rather than discovering it later, and ask whether keeping the dog lean changes the picture.
Does pet insurance cover cruciate surgery?
Accident and illness policies commonly cover it when the tear is not pre-existing and the waiting period has passed, but cruciate cover is the corner of pet insurance with the most fine print. Many policies apply a longer waiting period specifically for cruciate conditions, and once one knee has been claimed the other can be treated as pre-existing by some insurers. Check both of those clauses before you need them, because a knee that has already torn cannot be insured afterwards.
