I get this error: uninitialized constant Dog (NameError)
But I have no idea what this error means, heir is mys code:

if __FILE__ == $0
  # TODO Generated stub
  
  dog = Dog.new
  
  dog.name = "Fido"
  dog.age = 11
  dog.gender = "Male"
  dog.color = "Black"
  dog.bark;
  
end

My Dog class

class Dog < Pet
  
  def bark
    puts "w00f"
  end
end

My Pet class

class Pet
  attr_accessor :name, :age, :gender, :color
end

If those code snippets are from the different files, you need to require the file containing Dog from your main file and you need to require the file containing Pet in the file which defines Dog.

If it's all in the same file, you need to move the definition of Pet before the definition of Dog and the definition of Dog before the if __FILE__ == $0 block.

They are in diffrent files and I am brand new to ruby so do you mind make a code snip on how to do?

[sepp2k]

At the beginning of the main file, add a line which says require "filename" where you replace filename with the name of the file containing your dog class.

Similarly at the beginning of your file defining Dog, add the same line but this time with the name of the file containing the definition of Pet.

Eeh I was a bid to fast, but do you mean like this

if __FILE__ == $0
require Dog.rb
  # TODO Generated stub
  
  dog = Dog.new
  
  dog.name = "Fido"
  dog.age = 11
  dog.gender = "Male"
  dog.color = "Black"
  dog.bark;
  
end
