If a species has had a long history of experience with certain stimuli, especially those involving survival and reproduction, then to the extent that genes affect the ability to attend closely to such stimuli, natural selection leads to adaptations enhancing responsiveness to them.
The ethological approach asserting that
much of what animals know is instinctive or innate.
Theorizes that complex social patterns arise, develop, and sometimes even disappear based on their survival value.
Conflict Related Aggression
Occurs when an animal is exposed to an uncomfortable or uncertain stimulus or conflict.
Dogs tend to become aggressive towards humans not of their house hold; cats tend to become aggressive towards other cats in their territory.
form of behavioral therapy in which an undesirable behavior is paired with an aversive stimulus to reduce the frequency of the behavior
Involves the use of negative reinforcement to diminish a problem behavior. The goal is for the pet to link a the behavior with an unpleasant event and then avoid that unpleasant event. Example, if a dog barks excessively, then startling it with spray from a hose, but the dog shouldn't see the owner. This is used to to discourage the animal from displaying a particular behavior.
a behavior therapy procedure that conditions new responses to stimuli that trigger unwanted behaviors; based on classical conditioning. Includes exposure therapies and aversive conditioning.
reducing fear or anxiety by repeatedly exposing a person to emotional stimuli while the person is deeply relaxed
What is the Vet Tech's role in resolving animal behavior problems?
Providing behavior counseling services to clients
demonstrates the practice's commitment to supporting the human-animal bond. Behavior modification programs are currently the best way to treat behavioral problems and teach pets new habits.
Explain the need for humane restraint of animals in a veterinary setting.
By handling and restraining animals properly, you
make everyone else's job possible. You also ensure that the animals don't escape or injure themselves, their handlers (including you), or their owners. Finally, you provide the physical reassurance that's one of the animal's main behavioral cues in an unfamiliar, potentially frightening environment.
Using your hands to hold the animal in the desired
Since this method distresses animals the least, you'll want to use it whenever possible.
Employs such equipment as leashes,
collars, restraint bags, and poles.
These devices tend to upset
animals, so use them only when absolutely necessary.
Sedatives, tranquilizers, and anesthetics.
Vets consider chemical restraint the least desirable method.
Vets often complete routine physical examinations
with the dog standing.

direction as the dog, Grasp the dog under its neck, Place your other arm across the dog's back and pull the dog snugly against your body, extend the same arm to grasp the dog's opposite forelimb at elbow level with your right hand, Hold the forelimb at the elbow and use your thumb to occlude the vein by pressing in and slightly to the side, Use your other fingers to prevent the dog from jerking its forelimb back when the needle is introduced.
Restraint for Saphenous Venipuncture in Dogs
Position the dog in lateral recumbency, Grasp the upper rear leg just below the knee so that the skin over the vein is pulled tight to occlude the vein and prevent it from rolling while venipuncture is being made,
Restraint for Jugular Venipuncture in Dogs
Stand alongside the dog and place your right hand
under its muzzle, Point the dog's head towards the ceiling,With your left hand, grasp the dog's front legs
just above the feet and hold them together, securing
your grip by placing a finger between them, Pull the feet slightly to align them with the dog's nose.
Cat Restraint for Physical Examination
Allow the cat to stand or sit on the table.
Place one hand on the cat's shoulders, Place the other hand on its hips, Gently press it down against the table.
Cat Restraint for Intramuscular Injection
Grasp the cat by the scruff with your right hand, Grasp its back feet with your left hand, placing one or two fingers between the feet, Lay the cat on its side with its back resting against your right forearm, extend the cat's body by stretching its legs back and its head forward.
Restraint for Cephalic Venipuncture in Cats
Grasp the cat's head firmly under the jaw with your right hand, Extend your left arm around the cat's body and grasp the cat's left leg around the elbow, Hold the forelimb at the elbow and use your thumb to occlude the vein by pressing in and slightly to the side.
Restraint for Jugular Venipuncture in Cats
Wrap a towel around the cat's rear legs to prevent it from scratching you, Place the cat on its sternum at the edge of the table, its forelegs extending off the table's edge, Stand alongside the cat, place one hand under its nose, and point its head towards the ceiling.With your other hand, grasp the cat's legs just above the feet, securing your grip by placing a finger between the feet. Pull the feet slightly to align them with the cat's nose.
Restraint for Medial Femoral Venipuncture in Cats
Grasp the cat by the scruff with one hand, Grasp its back feet with your other hand, placing one or two fingers between the feet. Lay the cat on its side with its back resting against your forearm. Gently extend the cat's body by stretching its legs
back and its head forward. The upper hind leg is gently extended back to expose the medial femoral vein of the leg lying on the table. This vein must be held off once venipuncture has been completed to prevent a hematoma or
excessive bleeding from occurring.
Tail jacking usually serves to distract the animal from procedures performed elsewhere on its body.
Grasp the tail with both hands nearest the cow's body. Lift the tail up gently but firmly, taking care to keep the tail in line with the spine and not deflected out to either side.
Tail tying may also be necessary to prevent the animal from swinging its tail into your face as you work.
Locate the end of the last vertebra in the tail. At a spot about 18 inches from one end of the rope, lay the rope across the tail so that it lays over the end of the last vertebra. Fold the rest of the tail up and over the rope. Pass the short end of the rope behind the tail, making a long, sharp loop in the rope as you go. Bring the loop over the folded tail. Pass the loop through the rope that's looped under the tail. Pull the longer end of the rope to
tighten it. Use the longer end of the rope to tie the tail to the cattle's front leg or neck.
Serves to place an animal on its side.
Place the rope across the animal's back so that its ends fall between the forelegs and cross under the sternum. Pull the ends up and cross them over the animals back. Let these ends drop down so that they fall near the animal's rear legs. Pass the ends of the rope through the animal's rear legs and pull. This will cause the animal to lay down. Use the rope to guide the animal into position on its side.
Restraining Adult Sheep
Most examinations and minor procedures can be performed with the sheep placed up on its rump.
Stand on the animal's side. Place one arm around the sheep's neck at the shoulder and with your other arm, reach over the animal and under its abdomen as far as possible, depending on the animal's size. Gently lift the sheep and tilt it back onto its rump. Stand directly behind the sheep so that its back rests against your legs. Tilt the sheep's body slightly back so that it's off balance.
Restraining a Goat for Exam and Venipuncture
You can keep a goat still for a routine physical examination by lifting one of its front legs. Most goats will remain calm in this position. Holding onto the goat's chin or beard may also help keep it in position for short periods of time.
Firm Restraint for Goats
Position yourself alongside the goat. Reach one arm over the goat's back and one arm over the goat's neck. Grasp the legs closest to your body and gently lift up. This will force the goat off balance and onto its side.

Small pigs can be restrained on their backs in a V-shaped trough. The V-trough is usually made of plywood.
Lay the pig on its back in the trough. Attach a rope to one front leg. Pass the rope under the trough and tie it to the
other front leg. Repeat on the rear feet.
A rope with a loop at one end, tied with a slip knot so that the loop can be tightened.
Place one end of the rope in front of the pig's snout. Wait for the pig to open its mouth. When the pig opens its mouth, slip the loop into its mouth and push the loop quickly up so that it rests just behind the tucks. Tighten the loop across the top of the pig's snout.
The Vet Techs Role in Physical Exam
Prior to the examination, the technician must gather and
prepare any supplies and equipment necessary to perform
the examination. Whether you perform the physical examination with the help of a veterinary assistant, or assist the veterinarian in performing the examination, you'll need to know the proper type and degree of restraint each species,procedure, and individual animal requires.
