How do I know when to euthanize my happy old dog with tumors?

Updated on September 23rd, 2025

My dachshund is 10 years old and she has had tumors growing on the side of her mouth and other areas of her body. Today one burst on her neck but its just red hardly any bleeding. My question is. she is the most happiest dog. She runs around with the other dogs barking and playing as normal. Her appetite is great and her behavior has not changed in the slightest. She doesnt seem to be bothered by any of these. When do i make the decision to euthanize her?

This is an extremely difficult decision to make. I always try to look at a dog's quality of life to determine if they are still able to do most of the things they've always loved. If they are unable to do half of their favorite things, it is likely that their overall quality of life has declined and euthanasia may be warranted. Since your dog is currently eating, drinking, acting and playing normally, it does not sound as though her time has come. However, since one of her masses ruptured, there is a chance that it could become infected. Ideally, the mass would be surgically removed and biopsied. If surgery is not an option, she may need a course of antibiotics to prevent the onset of infection in the open lesion. If the open mass continues to bleed or begins to cause discomfort, you may need to decide if she should have surgery or euthanasia. If you are beginning to question if the time for euthanasia has arrived, consider discussing this with your vet to get their take since they have examined your dog and can provide some insight into her current quality of life. I hope this helps.

My dog has a bleeding tumor. How do I know when to put her to sleep?

I'm sorry that Millie has a malignant melanoma! I work for a home euthanasia service, so I face your question all the time. I recommend making a list of five things Millie loved to do, and if she is no longer doing at least two of them, then her quality of life has declined to a point where humane euthanasia should be considered. Her quality of life is most important to evaluate when making the decision as to whether or not to let a dog go peacefully. Dogs can be very stoic about pain, and they could be worse off than they are letting on. I would make that list of five things and look at Millie's quality of life to help you make that decision. If you'd like to talk further about this, I would be happy to consult with you. Just click the "consult online" button under my answer. Otherwise, I hope this helps you.

How do I know when it's time to put my senior dog down?

This is always a hard decision as our loved ones get older. My rule of thumb is to look for when they have more bad days than good days or they quit eating or quit getting excited about things that ALWAYS use to make them excited. From what you're telling me it doesn't sound like she is ready to be euthanized BUT you know her better than anyone and with her age and all of her problems, whenever you make that decision it will be be The Right time for her and you. She is so lucky to have such a loving family and to have lived such a LONG life. I hope this helps!

My senior dog has anal tumors but good spirit. When to put her down?

If your dog is happy and you feel that she has a good quality of life and can poop fairly easily, there is no reason to put her down. Listen to your dog. She will tell you when it is time to go. Your dog knows. Apart from that there are quite a few ways to control pain. 1) arthritis pain is probably the worst and worse than tumor pain at this stage. So if she is stiff and wobbly you may want to ask your vet about giving her an NSAIDs for arthritis (she needs to have normal kidney and liver parameters, though, but since you had surgery done recently, your vet may be able to use those blood work results). 2) if she cannot take NSAIDs, then there are other pain medicines available. The lumps under the skin either side of her anus could be filled anal sacs which could be expressed. They may not be tumors. Your vet may be able to stop the bleeding of the tumor by cauterising it, or you can get some Yunnan Baiyao powder or capsules and put the powder on the bleeding wound. It should stop the bleeding for a while.

My old dog has skin tumors. How do I know when to say goodbye?

Thanks for using Petco Pet Education Center, formerly Petcoach! I only see cancer patients and as you can imagine, I see terminal cancer patients on almost a daily basis. First of all, sorry to hear about Timmie. Give her lots of love, treats and all the good stuff that she deserves and wants. Usually regardless of the cancer type, I recommend treating any symptoms if they occur. Meaning that if Timmie develops any decreased appetite or nausea or vomiting or diarrhea, these are treated with medications. Otherwise, if you not pursuing cancer therapy, there is really nothing else to do. This decision is hard to make, no question. However, what I tell my clients is to consider making this decision if they think that quality of life has been severely affected. This means when Timmie does not seem to be enjoying herself anymore. You could consider doing it if Timmie stops doing 2 out of her 3 favorite things (that could be eating, playing, running, etc). Best wishes for you and Timmie!

When is it time to say goodbye to my senior dog with a tumor?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Brie! I think that if the mass is getting traumatized, is bleeding or infected or if it appears painful to her then it might be time. Especially if removing it isn't an option. Otherwise, if she is eating, drinking, not in pain, the mass isn't bleeding, she interacts with the family and can control her urine and defecation then I would give her more time. I always tell owners to measure the good and bad days and when the bad days out weigh the good then it is likely time. I hope this helps and I wish you and Brie the best!

My old dog has a leaking lump. Should I consider euthanasia now?

Poor Felony! If this lump is leaking pus, then it might be an abscess and not a tumor, as pus is a sign of infection. I think it's worth having Felony and this lump checked out by a vet. Should it be an abscess, then it can be treated with antibiotics. If it does turn out to be a tumor, then I would definitely assess her quality of life. I work for a home euthanasia service, so I face these questions all the time with my clients. I always recommend making a list of five things your dogs loves to do, and when they no longer do at least two of them, their quality of life has declined to the point where euthanasia should be considered. My professional opinion is to have Felony seen by a vet to see if the lump is an abscess. An abscess doesn't mean she has to be put down, and you could have more time with her, so it's definitely worth checking out. I hope this helps!

My old dog has cancer. How do I know if it's time for euthanasia?

Hi and thanks for posting. Oh I'm sorry to hear about Sophie. I know this is a hard decision to make and is never easy. It can be hard to say without seeing Sophie first, but if you notice Sophie is having more bad nights/bad days than good restful nights/good days, then it may be time to consider end of life care. Decreased appetite or disinterest in food as well as usual activities are also signs to look out for as well. I am happy to discuss further with you in a text consult as well. It would be helpful to get a little more information on Sophie so I can best advise you further. If I don't hear from you further, I hope this has helped a bit and I wish you and Sophie the very best.
