Physical animals aren't summoned. Because they are physical. The magickal action we call 'Summoning' is a spiritual broad phenomenon, and spiritual phenomenons always stay spiritual. Physical animals are physical, and physical objects and living beings always stay physical. Thus, physical animals can't be summoned. There is a big difference between spirituality to physical beings.
If you want to learn something and actually get to know something serious and real about the craft ; what you can do is to call your animal totem / spirit animal which is basically something that many magic practitioners do. This is a spiritual thing (spirit animals are spiritual beings, obviously), thus you can work with them and actually achieve this goal of you attempt to call you spirit animal and find your totem animal. This is not a part of the broad term summoning though, because that is a polite invitation.
