In September 2013, Maisy became suddenly and critically ill. Our blog readers rallied around us, providing us with the emotional and financial support needed to get through a very stressful time. Although I will never be able to pay you all back, I can pay it forward through Project Gratitude. Please email me at reactivechampion (at) gmail (dot) com if you have an individual or cause that you would like me to consider donating to.
For Project Gratitude this month... er, *coughlastmonthcough*... I donated to the Rabies Challenge Fund. This project is dedicated to determining the length of immunity the rabies vaccine provides. I love vaccines - LOVE THEM - but that doesn't mean I want to give them more often than I need to. The Rabies Challenge Fund is trying to extend the current rabies booster interval from a maximum of 3 years to 5 years and eventually 7 years. It would also determine an actual rabies titer standard, allowing titer exemptions to be written into law.
The Rabies Challenge Fund is at a critical juncture; they have recently gotten a commitment from a USDA-approved facility to complete the challenge tests, but they need money to do this. PLUS, they currently have a dollar-for-dollar match available, which means that I donated like twice as much money! Awesome.
If you are interested in minimal vaccine protocols, want to be part of science, or if you have a dog like mine with a wacky immune system that makes future vaccinations a bit scary, please consider donating! :)

I gave another dose of benadryl and the itching subsided, but the hives didn't. I figured we were in for a vet visit, but wanted to avoid the emergency vet because of Napi's stress/reactivity/aggression/whatever you want to call them issues. I know and trust our regular vet (Lake Harriet in Minneapolis- they are AWESOME for stressy dogs), but emergency vets are always a crapshoot.
But middle of the night, Napi woke me up by rubbing all over me, breathing heavy and fast, and looking like this:
|Swollen and miserable.|
He was surprisingly not awful. He did need a muzzle, and he did growl and lunge at the techs/vet initially, but by the end, he was... well not loud and not bitey or even wearing a muzzle! Which is impressive for him!
We don't know what he reacted to, but the hives, swelling, and itching are gone tonight, and I'm very happy for that. I'll admit that before Cesar and I moved in together, I secretly wished he didn't have Napi, but now? I wouldn't give him up for anything. I love him so so so much, and I am so glad he's okay.

|Insane in the membrane. Insane in the brain.|
But still, some dogs just aren’t right. From reactivity to anxiety to aggression, there are dogs who just don’t function well despite training classes and socialization and good intentions. Sometimes this is because the dog’s brain just isn’t wired right. Now, I’m no neuroscientist, but I do play one on the internet. And today, I want to share how stress can affect a developing brain, and why doing everything right may not matter if your dog came from a less-than-ideal background.
Science is pretty clear that stress in young mammals influences both brain development and physical growth. Stress can come in many forms. In children, there’s the obvious abuse and neglect, but then there’s the less obvious: poverty, housing instability, witnessing violence, growing up in bad neighborhoods, malnutrition, and so on. These chronic adverse events that the child and/or his caretakers have no control over changes the way the brain grows.
For dogs, such toxic stress during the early developmental period can happen in a number of ways. Puppy mills – and other deprived environments – are an obvious example of a stressful environment, but growing up in a shelter or a rescue can disrupt the growing brain, too. Sudden separations from human or canine caretakers, frequent change, environments characterized by sensory overload, and long periods of confinement are stressful. And even dogs from good breeders can be subjected to stress in the wrong circumstances: too much handling by a child, being harassed by another resident animal, or chronic medical problems on the part of the pup or the mother.
This does not mean that every dog from a puppy mill or rescue is going to have behavior problems. Indeed, if that were the case, people would stop getting dogs from these places. Some dogs have genes that are “turned on” by stressful events more readily than other dogs, making them more susceptible to the effects of stress. We see this in human children too; for some, stress creates a resilient brain, while in others, it creates a brain vulnerable to a host of behavioral problems.
So, just how does stress affect the developing brain?
First, it’s important to understand that stress is a normal part of functioning, and that overcoming a challenge creates a stronger brain and a sense of mastery. It is therefore important that children and dogs experience occasional frustration in doses they can overcome so that they develop the neuronal connections needed for a healthy brain. Not only is it impossible to shield your young mammal from stress, it’s inadvisable.
When a mammal experiences stress, the brain releases chemicals like cortisol and adrenaline. These prime the brain to be able to respond to potential danger. Once the stressful event is over, the chemicals dissipate, and the brain returns to its normal state of functioning. However, when stress is either prolonged or recurrent, the brain never fully gets rid of the stress hormones. This changes the way the brain develops.
Recent research has shown that there are notable differences in the amounts of gray matter vs. white matter in the brains of overly stressed children as opposed to those who experience normal amounts of stress. Basically, gray matter is responsible for higher functions like thinking and decision-making, while white matter is what connects the various brain structures. Chronic stress seems to create more white matter, which naturally results in less gray matter. In turn, this reduces the volume of brain structures that allow for rational thought in the face of potentially threatening events. At the same time, that increased white matter basically creates a short circuit in the brain. Even when there isn’t a stressor present, the brain may continue to respond as if there is. This tends to cause overreactions to things that aren’t actually dangerous.
Not only are the connections stronger between the lower brain structures that control emotional responses, but some brain structures become overdeveloped. The amygdala and other associated limbic system structures – which are associated with stress responses – are often enlarged, while the hippocampus and other higher brain structures – responsible for problem solving and rational thought – are smaller.
The end result is a brain that idles on high. It is more easily hijacked by stress, and will respond with more frequency and intensity to smaller stressors. The circuitry activates longer, and the recovery time takes longer.
In other words: your reactive dog’s brain? Is not like your normal dog’s brain. And as a result, his ability to process things that happen to him and respond to the world around him is going to be impaired. It’s not only unfair to expect him deal with the world without additional support, it’s probably impossible.
That’s not to say that your dog can’t improve. Science has shown that the brain is incredibly plastic – it can rewire itself and become more functional – but this takes a lot of time and effort. And even with the best interventions, we don’t know yet if all the scars left on the brain by stress can be erased. Sometimes adjusting the expectations we have for our reactive dogs is the kindest thing we can do.

I think it would be helpful to stop referring to depression and other mood disorders as “mental illness” because, although technically correct, that term has been stigmatized and it makes non-sufferers assume either that people suffering from mental illness are beyond help or that they just need to cheer up and/or try harder. Depression is a neurological disorder.People who have depression do not just experience disordered emotional responses, they experience disordered perceptions and engage in disordered thinking. This is because their brain processes are not functioning properly. Their neurons are not as they should be. Their hypothalamus, pituitary glands, and adrenal glands are being continuously triggered and their cortisol is not being inhibited; their amygdala (fear processing and fearful memory consolidation) may be enlarged as a result and their hippocampus (learning and memory) may be reduced in size. Their sleep patterns are abnormal and resemble that of someone who’s worked their entire lives 9-5 and now they’re being forced to work 3rd shift; their REM sleep comes on too soon and too often, they don’t experience deeper sleep stages as often as they should. Ongoing stress and sudden trauma trigger their symptoms, even after long periods of having recovered.This is not about being weak or failing to be strong. This is not about “feeling sad.”I think we need to put this to the fore every time this subject comes up. Depression is a disorder of the brain and body, not a psychological set-back or character flaw. Please be compassionate of others’ or your own suffering because it is real and deserves to be legitimized and treated.
I’ve posted this quote for two reasons.- Colleen A. Falconer
First, because this is an excellent description of just how depression (and many other mood disorders) is truly a biological illness, not something that’s “all in the head.” There are true physical differences in the brain, and these differences need to be medically treated. Because this description is so clear, it needs to be shared as widely. This platform is the best one I have to get the message out to as many people as possible, regardless of whether or not it is on topic.
And second, because it IS on topic. We humans are not unique or somehow special in suffering from the brain-based neurological disorders that we currently call “mental illness.” While it is true that diagnosing mood disorders in animals is tricky at best because animals can’t tell us what’s going on in their heads (which is why I prefer to use a veterinary behaviorist whenever possible), we can observe behaviors that suggest conditions like anxiety, compulsions, stress disorders, etc. In addition, there is no reason to believe that other mammals, whose brains look so very much like our own, couldn’t have abnormal neurons or brain structures associated with these diseases.
I’m not advocating for the over-medication of society, human or animal. I am advocating for appropriate treatment. Just as other medical problems can be treated with a multi-pronged approach (for example, diabetes often requires changes in diet and exercise in addition to medication), human “mental illness” can be treated through a variety of approaches, as can “behavior problems” in animals. But appropriate treatment can and does include medication, and just because it has been inappropriately prescribed in some cases does not mean that it’s inappropriate in all cases.
Mental illnesses are physical illnesses, and having one can be painful and affect one’s quality of life. These illnesses are often chronic conditions that require lifelong monitoring and maintenance; they aren’t something one just “gets over.” Maybe someday we will find a cure, but in the meantime, we are fortunate to live in a time when these illnesses can be treated. Please, do not allow yourself or your loved one to suffer needlessly.
