Post Surgery Instructions for Dogs and Cats

Download instructions: Post Surgery Instructions for Dogs and Cats

Please Read Carefully

Your pet has had major surgery. The surgery required general anesthesia where the animal is completely asleep and unable to feel or move. In female dogs and cats, the uterus and ovaries are removed through a small incision in the abdominal wall. In male dogs and cats, only the testicles are removed, not the entire scrotum.

Female dogs and cats will have a midline incision in their abdomen. Male dogs will have an incision just above the scrotum and male cats will have two incisions, one on each side of the scrotum.

• Your pet has a green tattoo by its’ incision. Please do not try to remove it. (Excluding male cats)

• Some animals are active after surgery, while others are quiet. It is very important that you limit your pet’s activity for the next 7-10 days. No running, jumping, playing, swimming, or other strenuous activity during the 7-10 day recovery period.

• Do not bathe your pet during the recovery period. Dogs and female cats have internal sutures and surgical glue is applied to the outside skin to provide strength. Any strenuous activity could disrupt

• Check your pet’s gum color when you arrive home. The gum color should be pale pink to red. The gum color should return quickly after you apply pressure to the gums above the canine tooth. Check the gum color throughout the day.

• Check the incision site at least twice daily. What you see today is what we consider normal. There should be no drainage. Redness and swelling should be minimal. If the incision gets dirty, clean gently with a cotton ball and water.

• Do not allow your pet to lick or chew at the incision. If this occurs, we recommend you buy and E-collar, which must be worn by your pet to prevent them from being able to reach the area. Please leave the E-collar on for a minimum of 5 days.

• Do not apply topical flea prevention for 7 days.

• Do not give Tylenol or aspirin for pain relief. These drugs can be deadly, especially in cats.

• If your female dog or cat was in heat at the time of surgery, you must keep them away from un-neutered males for at least two weeks. While they may be unable to become pregnant, they will still attract intact males for a short period of time.

• Male animals are virile for 3-4 weeks after surgery. Keep them confined so they cannot breed.

• When any anesthesia is used, stomach upset can occur. To help avoid this, we recommend you restrict the amount of food and water to which your pet has access upon returning home. Gradually increase the amount over the next 24 hours.

• Lethargy lasting longer than 24 hours after surgery, diarrhea or vomiting are not normal and you should contact a veterinarian immediately. Do not change your pets’ diet at this time, and do not give junk food, table scraps, milk, or any other people food for a period of one week. This could potentially mask post-surgical complications.

• Spaying and neutering are very safe surgeries; however, complications can occur. Minimal redness and swelling should resolve within several days. If it persists longer, please contact Texas Humane Heroes.

Please contact your regular veterinarian immediately if you notice any of the following:

1. The incision site is open and/or blood is dripping from the incision

2. If the incision appears infected, is swollen, or inflamed

3. Excessive swelling of the scrotum on male dogs. Male cats may appear as if they still have testicles. This is normal; the swelling should gradually subside during the recovery period.

4. Pale gums

5. Depression

6. Vomiting

7. Diarrhea

8. Difficulty urinating

9. Labored breathing

Should we let our female have one litter before spaying her?

No. Females should be spayed before the first heat, which usually occurs at 5-6 months of age. We stress before, since a female can become pregnant at that age and she is in no way ready for it. Pregnancy will place a great strain on the system, often resulting in birth defects, and she may not be able to nurse, resulting in seriously malnourished offspring. In addition, early spaying prevents later problems, including mammary tumors, uterine infections, and uterine tumors. If a female is allowed to go through a heat before spaying, those problems may still arise later in life because estrogen is stored in the system as a result of the heat.


How old should my pet be before the surgery?

Kittens and puppies can be spayed or neutered at 8 weeks of age as long as they weigh at least 2 pounds. If females are spayed before their first heat (which usually occurs when they are five to six months old), breast cancer can be almost completely prevented. Younger pets also recover more quickly from the surgery and experience less pain following surgery than older pets. In short – the sooner the better.


Is the surgery painful?

Yes, the surgery can be painful. However, we provide all pets with very effective pain medication that lasts upto 24 hours after surgery and offer additional take-home pain medication for purchase.


What’s an E-Collar?

An Elizabethan collar, E-Collar, or pet cone, (sometimes humorously called a pet lamp-shade or cone of shame) is a protective medical device worn by an animal, usually a cat or dog. Shaped like a truncated cone, its purpose is to prevent the animal from biting or licking at its body while the surgery site heals.


My pet just had a litter. When can I spay her?

We recommend spaying dogs when their puppies are 5 weeks old and can be away from their mom for the day. We recommend cats get spayed when their kittens are 5 weeks old as well. However, if you have an outdoor cat or a cat that you think may not be able to wait that long, we can spay them sooner. This is sometimes necessary because they can come back into heat and get pregnant while still nursing their kittens. It is okay for the moms to go back to nursing after her spay.


What does the tattoo look like and where is it on my pet?

The tattoo is 1/2 to 1 inch long, straight line in green ink located right by the surgical incision. It will fade a little after the skin heals.


Why tattoo pets?

The tattoo program was started so that we comply with the highest standards of the Spay-Neuter Task Force guidelines. These guidelines were established to protect our wonderful patients and insure that they are treated safely and effectively. The tattoo is meant to be a permanent identification that your pet has been spayed or neutered.


Can’t veterinarians tell if my pet is spayed or neutered without the tattoo?

Sometimes not. Of course this would only be an issue if your pet were lost or in a shelter without it’s medical history. With newer dissolvable suture materials, there are no stitches to feel in a female’s belly to indicate she was already spayed and if they have surgery at a young age, there is no scar to see. In male dogs, if you can’t see or feel a scar, there is a possibility that the dog still has testicles but they never dropped into the scrotal sac (cryptorchid). The doctor would open the male dog up like a spay to look for those testicles, a painful and unnecessary surgery that could have been prevented with a permanent identifying mark.
