Can My Other Dog Lick My Dog's Incision?
No. Keep other dogs from licking a recovering dog's incision for the full 10 to 14 days. Another dog's tongue adds bacteria, irritates the skin and can pull out stitches. Separate the dogs when you cannot supervise, and keep the recovery collar on the patient.
It is a loving instinct. Dogs lick each other's wounds as a social behavior, and your healthy dog is likely checking on their friend. Unfortunately, a gentle wash from a sibling is still a risk to a fresh incision.
Why do dogs lick other dogs' wounds?
Dogs lick for grooming, comfort and curiosity. A fresh incision smells different: antiseptic, blood and the chemical scent of surgery. Your healthy dog may be investigating, or trying to groom the area clean. Some dogs also lick their housemate's face and ears more after a vet visit, because the patient smells unfamiliar.
Is it safe for another dog to lick a surgical incision?
It is not. A dog's mouth carries a wide mix of bacteria, and an incision is an open door for the first 5 to 7 days. Licking also keeps the area wet, which slows closure, and rough tongues can fray sutures and staples. Even a few minutes is enough to cause irritation or open a wound.
The patient's own licking is the same problem; our article on what saliva does to a wound explains the details. Another dog's tongue is no safer than your own dog's.
How do I keep my dogs apart during recovery?
You do not need to isolate your dog completely, but you do need a plan for any moment when you are not watching:
Use a baby gate or a closed door to keep the healthy dog out of the recovery room.
Crate the patient or the other dog when you leave the house. See using a recovery collar in a crate.
Feed them in separate rooms for the first 3 to 5 days so there are no scuffles over food bowls.
Walk them separately for the first week. Two short, quiet walks are more manageable than one walk with two leashes. For rules on outdoor time, see walking with a recovery collar.
Supervised time together is fine once your vet clears light activity, as long as the collar is on and play stays calm.
Does a recovery collar stop another dog from licking?
It helps, but not completely. A collar blocks your patient from reaching their own incision. It does not block another dog from reaching a flank, belly or hind-end wound. An inflatable collar sits at the neck, so it will not shield the middle of the body. A soft recovery suit can add a barrier for a belly or flank incision; see recovery collar vs recovery suit.
The collar does protect the incision from your patient, which is the more common cause of problems. Use it plus separation, not one or the other.
What if the other dog already licked the incision?
Do not panic. Look at the wound in good light:
If the incision is closed, dry and the same color as the day before, leave it alone and check it again in 24 hours.
If the skin is red, wet or swollen, or you see any gap, call your vet. Do not apply ointment, peroxide or alcohol unless you are told to.
Take a clear photo and compare it again at the next check. Our guide to what to do when a dog licks an incision open lists the warning signs.
What if the dogs are bonded and the patient gets upset?
Many dogs cry or pace when separated. Give them a way to stay in contact without touching: a baby gate lets them see and sniff each other. Swap a blanket between the dogs so each has the other's scent. Short, supervised visits with a collar on the patient and a leash on the visitor work for most pairs after the first 3 days. If your dog is restless or whining, see why dogs are restless after surgery.
How long do I need to keep the dogs apart?
Plan on 10 to 14 days, or until the sutures are out and your vet confirms the skin has sealed. Most dogs can have short, supervised time together from day 3 or 4, then longer visits in week 2. Stay in the room, keep play calm, and separate them again the moment the healthy dog starts sniffing or licking at the incision. A short routine, such as 10 minutes of gate-side time, a calm treat for each dog, then back to their own spaces, keeps both dogs settled.
Other dogs and incisions FAQ
Can my other dog sleep next to my recovering dog?
Only with supervision and after the first 3 days. Overnight, separate them. Licking at night is the most common way incisions get disturbed.
Will my healthy dog stop licking on their own?
Often it fades by day 5 to 7 as the smell changes. Until then, treat it as a risk and use a barrier.
Does the healthy dog need a collar too?
Usually not. A short-term barrier is usually enough. If your dog will not leave the wound alone, a soft collar on both dogs for a few hours is an option.
Can cats lick a dog's incision?
Treat cats the same way: keep them apart until the incision is closed and your vet clears it.
Make sure the patient is protected first. Browse our recovery collars for dogs, and set up a separate recovery space before surgery day.
