Is it safe to spay my 4-month-old pug during FHO surgery?

It is always best to spay your dog when they are young if you are not planning to breed. Yes, brachycephalic need special care with anesthesia but vets know this and take special precautions. If you don't spay her you are risking her gettting mammary (breast) cancer and/or pyometra (life threatening uterine infection). It is much worse to have to put her under anesthesia later when she is sick rather than now when she is young and healthy. https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/

Yes, it is most likely mammary (breast) cancer. Very common to happen in dogs that are not spayed. That is why we recommended spaying dogs early in life. 1. I suggest you find a vet that will do both surgeries at once. There is no sense in doing two surgeries a month apart. They can both be done safely at the same time in most cases. She may be one of those cases that the mass is extensive and that is why your vet does not want to do them at the same time. I don't know since I have not examined her myself but in most cases I would do both surgeries together. Just my opinion. 2. You need to get her spayed, even at 8 years old. If you don't, then she may end up with more mammary tumors or a pyometra or she may pass away. Yes, a blood test before the spay is indicated absolutely. 3. It should not change her much. If you don't do it then she can certainly die just like a person with breast cancer so you really have no option but to have it done. Hope this helps. Best wishes.

Typically, the first heat cycle will occur between 6 and 9 months of age. It really depends on the individual dog and there is no way to determine when your dog will go into heat for the first time. You can have her spayed at 4 months, but you will likely need to take her somewhere else if your veterinarian won't do it. Waiting until 6 months should not pose an issue though. It's the age a large percentage of dogs are spayed or neutered.

No, it is common to combine procedures together, such as a lump removal and spay. It's safer for Honey to have anesthesia once for both procedures, as putting her under twice may have more risks. It's also common to give vaccines and a microchip while doing a spay.

I think it will not be an issue. If anything it will likely prevent further vaginal prolapses, as with spaying the supply of estrogen that was part of the cause, will cease, I would wait until approx, 2 months after her last heat (which probably was when she had the prolapse, right?)

I am so sorry that you are exeoeriencing these problems with Wiggles I am sure it's very upsetting. Because mammary tumours are Hormone linked I would advise spaying her when she has the tumours removed. The last thing you would want is for Wiggles to have another mammary tumour in the future and therefore another surgery. For anaesthetics for older dogs many precautions are taken. Your veterinarian will discuss these with you to help put your mind at ease. They include blood pressure monitoring and intravenous fluid treatment before, during and after the surgery. I believe this is the best course of action and I send you the best of luck.

Great question! Yes, it is safe to combine anesthetic procedures in a dog. Dogs can safely be under anesthesia for hours depending on the procedure needed, although in her case, it shouldn't take multiple hours for these procedures to be done. The vet wouldn't have recommended doing both at the same time if they didn't feel it was safe to do on her. Speak with your vet about your concerns, but this is fine to do. I hope this helps!
