Why do vets want to give jabs yearly?

Jabs are yearly because of the way the immune system works. There are two levels of response, the passive (protection by skin), and the active (which is where the body makes the antibodies).

If you think of it like a army, the passive is like
a border with sentry towers, and the active would be the battilions within the fort protecting the capital. When the sentry spots an enemy it sends a message to the fort asking for reinforcements (antibodies), but this takes a few day for them to arrive as they have to be trained and equipped first. In this time the enemy overwhelms the sentry’s and invades the country.

Now what a jab does is to “present” some enemy to this sentry so that it sends the message to the fort to ask for reinforcements. But with the jab their is no risk of invasion so the body has time to create the reinforcements (antibodies). Now these antibodies are there and sit in the fort trained and equiped ready to respond, instead of taking a few days to arrive to back up the sentry, they arrive much faster so the enemy is destroyed sooner.

However just like in a human army, without training they would get bored, desert, quit so that over time the number waiting to respond falls to a level where they would not be able to defeat the enemy. This is why yearly jabs are given to “train” this response and keep it at a effective level.

The drug companies have done research counting the number of antibodies over time and the effective number and based on this calculated the time the jab needs to be given. It is possible for a vet to do a titer-count to check an animals number of antibodies to see if the vaccine is needed – BUT this test costs more than the vaccine and if it is low the vaccine still needs to be given.

What happens when a dead animal bloats?

So today in a quick break from revision I wanted to share this video that was sent to me earlier today as a bit of cheer.

When an animal dies, and is left in the sun the decomposition causes the release of gas within the body – especially from food that remains in the digestive tract. This can cause the body to swell whch is known as bloat.

I’ve seen it happen personally with a horse, it was very entertaining to see a friend get covered in crap but this video is from a zebra. And for it to be a hungry leopard that causes the explosion when it finds a zebra carcass in the Djuma Private Game Reserve in South Africa.

It was caught on camera too, so if you have the stomach to watch (it is bloody!) check it out here:

For anyone more curious, it takes a good few bites because the abdomen is pretty tough, there is a layer of skin, then muscle, then the peritonium as well. Muscles tend to solidify and get really touch on death because of rigor mortis. Also where the leopard was biting is around where the bladder is located so the jet could also be urine.

How to cook a dog – hot car recipes…

So today we are going learn how to cook a dog, this is a seasonal dish for car owners easiest to prepare during the summer period and can be done in as little as 10 minutes during the sun’s peak hours.

Now the entire goal of the cooking process is to overwhelm the internal regulation of the dogs temperature which is controlled in the brain so we need to raise the temperature to above 41 degrees Celsius. The best way to do this is by parking the car in direct sunlight, and limiting the sources of ventilation – simply leave the window open a slit which will ensure fresh oxygen whilst not lowering the temperature of the car.

You can tell when this is starting to occur with heat cramps and heat exhaustion where the dogs’ activity decreases and they cannot walk without pain. At this stage you are well on your way to cooking your dog and have successfully overcome many of the dogs protective response systems…

  • The behaviour mechanism is overwhelmed as the dog cannot move to a cool area…
  • The blood flow to organs decreases and flow to the skin increases…
  • There is no evaporative cooling as the air exchange is not high enough because we leave just a slit of the window open… and then this only really works when the tongue is wet.
  • Radiation and convection (movement of heat from hot to cold) do not work as all the extra heat has nowhere to go, the environment is all hot…

So just keep going, it’s only going take a little while longer until your dog is cooked. The dogs’ body still isn’t ready to give up though, and a big response from the cells will try to protect the tissue for the injury that is coming.

Now we are here, the bodies organs start to shut down, the temperature causes the cells inside these organs to die. Here the enzymes start not working so cell energy production changes to not use oxygen anymore, we need to be careful here as the pH will change to acidosis.

The brain cells start to die as well now, there is also big swelling, and now maybe you will see some seizures or coma.

The cells from the lining inside the stomach and intestines die, and break off into the gut causing loads of bleeding. The same with the kidneys with cells from the kidney dying and breaking off. Most important here is making the liver is properly cooked, this is where the cells for blood clotting are made so if we get rid of this then we can get rid of all the blood from the body by uncontrollable bleeding.

If you are here your dog is pretty cooked. How long did that take? 15 minutes? 30 minutes?

If you suspect a dog is suffering from heatstroke you need to get them cooled and to a vet

The best way is to transport them on the backseat of a car sprayed with cold water and with both windows open to help the cooling process. DO NOT USE WET TOWELS – this is a myth and will in fact trap the heat inside the body.

If you have to go somewhere not allowing dogs,, it may be kinder to leave them in the shade at home.
