Are we being exposed to mold?

I live in a duplex in Ohio with my husband and 3 children ages 6, 2, and 1. For over 3 months now we have all been coughing and wheezing. I believe this is due to either mold exposure or exposure to the smell of dog feces and urine. Our neighbors on the other side of the duplex at one point had 5 puppies who peed and pooped all over their house and they would leave it there for days. Then they started putting them in the storage closet when they would leave for hours at a time and the dogs used the closet as their own personal bathroom so now the smell of their dogs is heavily seeping into our house.

We have all be coughing and had colds and my daughters have had ear infections. My husband and I get headaches non stop and he has ever had nosebleeds. My 1 year old son has had a runny nosy for 2 1/2 months now. I have had migraines and I am always feeling fatigued. The list goes on and on....

As for the mold, I am pretty sure there is mold growing in the storage closet where the urine seeped through to our side. I have spoken to the landlords and they haven't done anything so I have begun contacting the health department and code officials.

My question is could repeated exposure to mold or dog urine/feces cause the symptoms I mentioned above.
