Top Dog
Type: Activity
Learning Strategy: Case study
Topic: Inheritance of characteristics
With Crufts behind them for another year, breeders and judges are now preparing for smaller dog shows all over the UK. Many of these rely on the strict selective breeding of pedigree dogs. This can lead to chronic genetic problems and diseases. Is pedigree breeding ethically acceptable? This activity gives students a chance to decide for themselves.
This activity is designed to be used in conjunction with Simpletons: a tool for teaching ethical thinking. We suggest using Simpletons to teach students how to think from different ethical perspectives. Top dog then allows students to practise the same ethical styles in a different context.
11-16 How Science Works:
4b: consider how and why decisions about science and technology are made, including those that raise ethical issues.

Running the activity
changed considerably as a result of selective breeding. Tell students that they will consider whether pedigree selective breeding is ethically acceptable.
Display page 2 describes the science of pedigree breeding.
Give each student – or pair – a copy of page 3. Ask each student to complete the speech bubbles, bearing in mind the ethical approach of each person. It may help to remind students of the ethical approach of each 'Simpletons' character ('Hiram' – utilitarian; 'Lucy' – rights-based; 'Madge' – care-based; 'Brad' – self-centred) and ask them what that character might say. Students then choose the view they most closely agree with. Then get students into small groups – each representing a variety of views – and ask them to debate the issue for a TV-style discussion, or lead a whole-class discussion on the question: Is pedigree dog breeding cruel?
Note: this activity assumes that the ethical approaches described in the Simpletons activity can be applied to animals besides humans (a whole debate in itself!).

Incorrect pictures
Jul 12th, 2012
I hope that the incorrect dog breed will be corrected.
The picture is a Basset Hound rather than Bloodhound, although they share some facial characteristics they are quite different dog in size and shape.
A good activity but a shame the basic information is incorrect.
This was something pointed out to me by students as well as noticing it as soon as I viewed the resource.

Nice little activity.
Doesn't take too long and is good for the lower groups. Some of my year nine were able to think up some really good arguments.
NB I didn't use the Simpsons thing; I just asked the students to say how four different people might respond.

Facts wrong
Nov 14th, 2010
I've always found the activities on upd8 great to use but I'm rather disappointed with the science facts in this activity and the bias.
Possibilities have been presented as facts - particularly for the Chow Chow and Bulldog. Should a science website be perpetuating the myth that Bulldogs can't self- whelp or that every Chow Chow gets entropian .I dislike the definition of pedigree breeding as being the breeding of 'closely' related dogs when in fact you've descibed line -breeding (in-breeding). Pedigree breeding by definition is simply the breeding of one KC registered Bulldog to another and although some breeders carry out line breeding(!!) most know that it would only be storing up problems for the future and wouldn't do it.
This was clearly not devised by someone that knows about dogs.

Good activity - provoked lots of discussion with my Y8's. The lesson actually ran over as they debated selective breeding and all wanted the last say!

Good activity.
I adapted it a little with starter & plenary, so its a lot to fit in to a 50min lesson but the kids found it enjoyable and challenging.

Inheritance and selection - year 9

My students really enjoyed this approach. The less able ones where immediately stimulated by the dog theme and both classes really enjoyed the group work. We shall undoubtedly teach this again to our KS3 classes.

Hi I'm a student.
Can someone post some answers for the pedigree ethics activity. The link articles do not give you a real insight into the different opinions.
Thanks.

Adapted this with my Y9 - they loved it. It really did get them thinking; only wish we'd had more tiime to explore, in greater depth, the moral issues surrounding selective breeding. Great stuff.

i used this with my year 10 entry level science class and we had a very interesting ideas forwarded about the science and ethics behind selective breeding even though they are very low ability. i extended it by them choosing a particular animal to selectively breed.
