Anatomy: Rabbit vs. Dog

Digestive System

Dog :

A dog's normal heart rate is about 100-160 BPM

Small breeds and medium-large sized breeds have a 60-100 BPM

Puppies under one year can range from 120-160 BPM

Rabbit:

Food travels from the mouth, down to esophagus, to the stomach, then the small intestine which absorbs nutrients from the food, during the traveling the enzymes break down the food.

The colon diverts it into caecum to process which is when the colon forms the waste into rabbit droppings.

Rabbit teeth are designed for grinding herbivorous substances

Dog:

The food travels from the mouth to esophagus, to small intestine, then to the large intestine just as the rabbits does.

Dogs have canine teeth and a stomach designed for digesting meat.

Heart

Rabbit:

A rabbit's heart rate should be 120-150 beats per minute

Rabbits tend to stress very easily which can cause their heart rate to increase to over 300 beats per minute. Rabbits are also prone to cardiac heart diseases.

Muscular System

Rabbits

Muscles are built for speed

Skeletal System for dogs

• The canine skeletal system is made up of 319 bones

Both

Urogenital System

In the wild both rabbits and dogs have erect ears where as domesticated breeds have been selectively breed to have loppy ears

• Their front and hind legs match in size

Skeletal System for rabbits

Muscles are built for endurance

Canines

• the size and configuration vary in different breeds greater than any other species

• The rabbit skeletal system is made up of 222 bones

• Hind legs are longer than front legs which is why they're able to hop

• They have seven tarsal bones

Kidneys filter out impurities from blood

They maintain the correct balance of water and electrolytes in the body.

Rabbit: The urine of rabbits is orange or brownish red color because of dietary compounds plant pigment.

Dog: The urine of the dog is typically a clear yellow color.

I believe that dissections are; for most

part, unnecessary. This is because there are

plenty of online alternatives nowadays. I feel that

once one dissection has been completed by a student,

the need for more after that is non-existent. This is because many animals have almost the exact same internal anatomy. Additionally, many students are desensitized by dissections. They begin to look at the specimens as objects and not living creatures. Many of the animals used for dissections are also not treated with respect while still living because their sole purpose is to live until they're big enough to be prodded at by school kids. Participating in many dissections today, I feel is just selfish. It is nothing other than humans being the superior organisms taking advantage of less-advanced ones. I do feel that one dissection is a very good learning experience, but animals should not be raised for the sole purpose of being hacked apart by students. Shelter animals that

have been uthanized due to overpopulation are

more than enough to learn from, if only

more shelters would get

involved.

The gestation period of a rabbit is 31 days; Dogs 58-68

They are pregnant for 1 month: Dog 2 1/2 months

Ethics of Dissection

Ashlynn

I fully support dissections for the animal medical field courses. A few reasons I would agree is because it is much easier for the students to learn if they can see the real thing. Also, it teaches the students to respect the animals and what they are or have been used for. Lastly, dissections can also be a good way for the student to know if they will be able to handle these types of things before they get into the field. Therefore, as long as the students use the animals respectfully I believe dissections are beneficial to the learning process.

Anatomy: Rabbit vs. Dog

Dog:

The dog brain is on average 72 grams

The size varies from bred to bred.

The dog is as smart as a three to five-year-old child like the rabbit

The Brain

Rabbit:

Rabbits are as smart as a three or five year-old human child and can perform most of the tricks as a dog can.

Additionally, the rabbit brain is 5 cm long and 12 grams.

Even though, the people of PETA are against dissection, dissections are needed for the learning of both the teachers and the students. I understand the concerns by the people of PETA fully, but what they need to understand is that without these few animals giving there lives for people to learn on, young veterinarians would be "walking in the dark" when cutting open a live animal; most likely killing that animal. Now with further knowledge on the inside of animals, new vets can save the lives of living animals and be less bothered when they see the inside of the animal. Therefore, it is essential for animals to be dissected for research, because the process helps veterinarians learn, what killed animals, and it helps young veterinarians learn, what is inside a animal before they move on to live animals.

Hearing

Dog:

67-45,000 Hz

Rabbit:

360-42,000 Hz

Rabbits' ears acts as satellite dishes to amplify minute sounds that may indicate a predator approaching.

Fun Fact:

Rabbits are not able to sweat through their paws like dogs,so they use their ears as a sort of tool to maintain temperature homeostasis.

Although many may not agree with dissections, it is very beneficial to future veterinarian's. Animal dissections are important because they play a huge role in better understanding the information at hand because it gives an authentic and hands on experience with the system.This helps many students retain information on the system they are studying. Dissections are an essential part of learning anatomy and physiology because dissection is the study of the structure, shape, and functioning of organs and their relation to one another in living organisms.

Vision

Rabbits:

Lateral-eyed

Nearly 360 degree field of vision

Few blind spots

Limited near vision (farsighted)

Color vision

Great night vision

Dogs:

Color blind to red and green

250 degree field of vision

Near sighted

Binocular vision

Great night vision

Rabbit:

Rabbit hair can be divided into three types:

Guide hair: external, long and rough

Guard hair: seals coat, four of these surround one guide hair

Down hair: inner-most coat, insulation, very dense

Hair

Dog:

A dog's hair can be double-coated; which means it is made up of a soft under coat and a top tougher coat.

The top coat helps to repel water and shield from dirt

The under coat serves as insulation.
