1. Happy Thursday! Today: Complete Dogs Decoded Activity: Artificially Selecting Dogs

3. Half descended from the English Foxhounds that were brought to America in 1650 English hounds were crossed with a French hound that George Washington received as a gift from Lafayette Excellent hunter of wild animals Great speed and an excellent sense of smell Can run at high speed for long periods Has a musical bay that is easy to follow Still used as hunting dogs, companions and watch dogs

4. Think-Pair-Share What are some traits would humans try to select in dogs? Remember: All dogs breeds are the same species: Canis familiaris (so can interbreed and produce viable offspring) There are over 400 different breeds of dogs A breed is a subspecies It takes many generations to get a new breed Many of today’s breeds are a result of artificial selection/selective breeding

5. What if… You want a dog that can hear a polar bear approaching and alarm the bear so that it will turn back. Which of the following dogs would you selectively breed to produce offspring that would be most effective in scaring away a polar bear?

6. Dog Traits Physical traits Function/significance 1) Smell Above average olfactory receptors = 2) Sight Above average number of rods = 3) Hearing Long pointed ears = 4) Speed Long legs = 5) Endurance Large heart = 6) Strength Large muscles = 7) Coat color 8) Hair length long hair = short hair = Strong smeller Excellent eyesight Very good hearing More oxygen = very good endurance Very strong Fast runner Keep dog warm; gets heavy when wet Keep dog cool; does not get heavy when wet

7. Dog Traits Behavioral traits Trainability High trainability = Low trainability = Disposition Vicious = Compatible = Bark Loud bark = Quiet bark = learns quickly; follows directions; does not get distracted easily distracted; have to keep on a leash most times; crazy will attack if commanded; is not afraid of other dogs or people friendly; likes to help others; very social can be used as a warning won’t scare others

8. Your mission – Part 1 Create a new breed of dog that will accomplish the task listed You will work with a partner and choose the parents that you think will produce offspring that can achieve the task 1.Read the cover sheet 2.Fill out the top part of the “Ownership Card” 3.Choose the desired features of your new breed

9. Your mission – Part 2 1.Look at the “Dog Breeds” handout 2.Identify which two breeds you should cross to get the traits you want 3.Write the breed names you chose in the blanks 4.Describe, in detail, the reasons for your selections. 5.BE READY TO SHARE YOUR SELECTIONS AND REASONS WITH THE CLASS 6.Choose which dog will be the mother and which will be the father 7.Each breeding pair will produce three puppies 8.Each puppy may inherit features (traits) from the mother OR from the father 9.Determine this by a flip of a coin: Heads = the female's (mother's) feature, tails = the male's (father's) feature
