Fun little dog exercise I did a while back!

dog.rb

# Save this file to your computer so you can run it 
# via the command line (Terminal) like so:
#   $ ruby shakil_the_dog.rb
#
# Your method should wait for user input, which corresponds
# to you saying something to your dog (named Shakil).
 
# You'll probably want to write other methods, but this 
# encapsulates the core dog logic
def shakil_the_dog
	print "Shakil: "
	5.times {print " Woof!"}

	finished = false
	until finished== true
		puts "\nWhat do you want to do? \n a. Speak to Shakil. \n b. Woof back! \n c. Tell him to stop! \n d. Be a cat! \n e. Give him a something he'll like! \n f. Make him leave! "
		choice = gets.chomp.upcase!
		print "You choose option #{choice}! "

		case choice
		
		when "A"
			puts"What do you want so say to him?"
			phrase = gets.chomp
			aSpeak(phrase)
		
		when "B"
			puts"You: "
			bark()
		
		when "C"
			mustInclude#  = "Shakil STOP"
			puts"If you explicitly use his name and advise him to stop he will not respond back with a bark."
			advise = gets.capitalize.chomp
			if advise == mustInclude
				puts "Shakil: . . . "
			else 
				puts "Oops! Try saying his name and yelling at him to stop!"
			end

		when "D"
			print "You: "
			purr()
			print "Shakil: "
			bark(5)

		when "E"
			puts "Say treat!"
			sayTreat = gets.chomp
			until sayTreat == "treat"
				treat()
			end
			
		when "F"
			puts "He left. You kicked him out by saying go away!"
			finished = true
		else 
			puts "Invalid."
			bark
		end
	end
end

def bark(x=1)
	x.times{print " woof!"}
end

def purr
	puts "Meow..."
end

def aSpeak(saySomething)
	puts "You: #{saySomething}" 
	print "Shakil: "
	bark()
end

def treat()
	puts "treat"
	puts "Shakila.... *waiting for treat*"
end
