Yard Materails (West Mesa)

Looking for materials to reinforce my fence and to create a gate. I have three dogs as my protection and they are great. However, they from time to time get out under the fence and/or jump and bark at the front gate. This is.a rental property and landlord will not supply. I was laid off and my partner is paying all the bills which is why I am asking instead of just going to the store. Thank you!
