Hi Tom,nice to meet you in this social network,I think you must have  paied  a lot of time on practicing Mandarin pronounce,and you did it well,it`s something like the Chinese pepole start to learn English,at the begin we used to focus on the English pronounce,I think it`s a useful way to go deep into the language,but after that I suggest you to learn some Chinese characters,maybe it`s hard for you now,but it`s really a good way to undersand and remember.

back to your composition,in the Mandarin,when we talk about an animal,we use "zhi1",for example:yi1 zhi1 gou3\yi1 zhi1 niao3(bird).but when we talk about a beast or some animals have big body,like a lion or a elephant,we use "tou2",wish those informations are helpful for you:)

and you don`t need to put "shi4" ahead of "jiao4",it`s unnecessary.
