>> James Jacobson: Okay, well, let me ask you this question, which will be more based on your experience and your feelings. Cause I think of you, sort of as a Dr. Doolittle, Demian: do dogs know when they're dying? 

>> Dr. Dressler: Yeah, I think so. I believe so. 

>> Announcer: Welcome to Dog Cancer Answers, where we help you help your dog with cancer. Here's your host, James Jacobson. 

>> James Jacobson: Hello friend. And thank you for joining us today for a very special Question and Answer episode with Dr. Demian Dressler. We get a little deep kind of quick with Dr. D, which honestly happens more often than one would assume. Today's question comes from a listener whose name is Justin, who wrote in to ask the following: what to dogs do when they're about to die?

What are some of the signs that they are in fact, getting ready to leave us? And Dr. Dressler surprised me with two very different answers than I expected. Let's listen in. 

Dr. Dressler, thanks for joining us today. We're going to go back to the mailbag and here is a question that was sent in from Justin.

I thought it'd be really helpful for our listeners. The question is pretty simple, but it may have some interesting meanings for you: what do dogs do when they're about to die? 

>> Dr. Dressler: It's a tricky question because there's all sorts of different ways to die. And if we have to look at cancer, there's all kinds of different ways to die with cancer as well.

So that's a very tough one, but what I will say is the following: you want to look at, first of all, general signs of illness and the illness is going to be the thing, usually, that precedes the dying part. It's really unusual for an animal or a human animal to have zero signs of illness and then die.

That's the minority of the time. It does happen. You can have sudden cardiac events, you can have strokes, you can have infarcts, you know, things like that do happen. But again, that's the exception and not the rule. So first of all, we have to say, okay, well, what are some common signs of illness that my dog is sick, whether it's cancer or some other type of syndrome.

And so we're looking for coughing or sneezing or vomiting or diarrhea or increases in thirst and increases in urination and a loss of appetite and a loss of energy level and a loss of a desire to do its normal things. So that's your short list on signs of illness. There can also be physical discomfort perhaps as a piece of that, which is again, an whole other subject.

So then we say, well, how do I know when my dog is going to die based on the signs, that's very difficult to say. And the reason why is because nobody has a crystal ball, we don't have a date stamp and neither does our dog. And what's interesting is some of these old dogs, particularly the ones that tend to sort of cling to life, and I think guardians, you know who I'm talking about, if your dog is one of those dogs, because they tend to get a little bit irritable. 

>> James Jacobson: They get old and irritable

>> Dr. Dressler: Yeah, they get old and they get crotchety, but it's a fighting thing. It's a manifestation of being a fighter, as opposed to sort of these old dogs who kind of roll over and give up the ghost.

I find that dogs that are very passive in life tend to be passive, clinging to life. Also. They tend to exit more quickly. Where the dogs that are more tenacious and stubborn, kind of like people, they seem to just go on and on. And, and if you look at the end stage of these dogs, they'll go through these cycles where they will get sick, apparently sick, and everybody will think, well, that's it for Fluffy. And Fluffy, all of a sudden will claw back and start acting normal again. And then a couple of weeks later, Fluffy's not doing well again. And it's not that the disease itself is changing. I think it's just that the response that disease tends to be cyclic.

So there's that pattern I see a lot. Then if you get to kind of the tail end and you're getting into dying of natural causes versus, uh, humane euthanasia decision, which is a whole separate subject. That's a separate show, as I said. Yeah. One of the most common things I see will that they will get disengaged with people they'll sort of go inwards and a lot of times they'll want to go outside.

They have an instinct and I'm not sure what the point is, but they'll often go outside and go hide or find a separate place to die that's different from their den or their home or something. It's something about being in the air and being in the elements, I think, is connected with this final phase of departure.

So those are two things, I think that I've seen more or less consistently, I don't know about every time, but one is they'll sort of turn inwards in terms of their focus. They'll kind of not really be as present at all. And you'll see them sort of staring off into space and kind of like they're getting ready for the big Exodus to wherever dogs go.
And then they'll also tend to gravitate towards the elements, the natural elements. So. Air and sun and maybe snow, things like that. 

>> James Jacobson: Besides those two, any other signs that you've noticed that tend to happen? Obviously, every dog, every experience is different. 

>> Dr. Dressler: The problem is, is that it's a simple question with a complicated answer that has many, many different answers, and those are the two commonalities that I can think of because then you have to get into the specifics of what exactly is wrong with them because a dog with a bleeding tumor in his spleen is going to die in an entirely different way than a dog with a brain tumor. They're totally different in terms of how they look and what the disease entity does to the animal. So it's a little bit hard to make a general statement.

And so the question is predicated on the idea that death is a consistent process when it actually, the number of differences in the dying process, far out number, the number of similarities. 

>> James Jacobson: Okay. Well, let me ask you this question, which will be more based on your experience and your feelings. Cause I think of your sort of as a Dr. Doolittle, Demian: do dogs know when they're dying?

>> Dr. Dressler: Yeah, I think so. I believe so. I don't know if you can say that across the board a hundred times, it's kind of like, do people know when they're dying? It's the same thing. It's again, the fact that we call them dogs, you use a single word for them, sort of misses the point. These are individuals, just like people are individuals they're different.

So they're going to know different things and they have different awarenesses and they have different experiences in the same exact way that people do. But yeah, I think that most of the time the dogs seem to have an awareness that they're going to be exiting because they're sentient beings. I mean, they know when they're hungry, so why wouldn't they know when they're dying, you know?

>> James Jacobson: Okay. And then in The Dog Cancer Survival Guide, you talk about like in the wild, they would just kind of go off on their own and hide. And I'm assuming that that natural tendency of wolves for example, is something that you're seeing when dogs want to go off and spend more time outside. 

>> Dr. Dressler: Yeah. I mean, it could be, there's a couple of different reasons so that I can hypothesize as to the why's there.

And I don't want to get too sort of spiritualist in that, but I could. But if you just look at it very basically: having a corpse in your living room is unsanitary. So that's the first thing. It's probably better. If you're going to become a rotting body, to rot elsewhere. Furthermore, there's carrion eaters and there's other predator species that might actually be happy, either eating you or eating your fresh remains.

And it's not good to bring those predator species close to your babies and close to your family and your pack. So we'd suspect that's the main reason why that instinct is there. I think. The other thing too, you know, again, dogs are sentient beings. They can feel, you know, there are, there's sensations that I think feel good and there's sensations that I think feel bad.

And I think being in an open space is a good place to be, particularly when you're starting to depart. When I say an open space, that doesn't mean that they don't find little enclosures. That's not what I'm getting at, but like fresh air and being connected with the elements in that way. I think they sort of go back, maybe there's like a Rolodex, not only of their life, but also the species existence where they may be. It's a very primal thing, dying. You know, the entries and the exits here are very basic processes. And I kind of think that because there's a very, very old processes like being born and dying are very, very, very old, I kind of think that maybe they revert to an older way and maybe they're more comfortable being in an outside environment as a consequence of that, instead of being in front of your iPad. 

>> James Jacobson: I have a theory, it's, you know, it's one of these profound things and it's impossible to validate, but I sense that dogs find their sense of spirituality by feeling connected to the sky, by being able to look up at the natural sky and just be outdoors.

>> Dr. Dressler: Yeah. There's something about the openness. Yep. I agree. 

>> James Jacobson: Yep. Okay. Well, thank you very much for that insight. I appreciate it. Thank you, Dr. Dresser. 

>> Dr. Dressler: You're welcome.
