Fence Repairs - from damages from my companion dog

[Collette F.]

I am half way thru a Purchase Agreement for my manufactured home.   2 years ago, I received a companion dog prescribed by my doctor and submitted this to park management/owners.  He is larger than the normal pet allowed.  His breed is Cane Corso mix but many residents argue that he is a pitbull.  My dog is very mello, calm and normally sleeps all day if I'm at work.  When my son moved out and my companion dog is home alone now, he has managed to get out of our house in various different ways looking for me or anybody, but he is afraid to be in the house all alone.  

There was 1 incident that my dog has figured out that the flimsy fence between my neighbor and I are more like a curtain that he can go into his yard.  The neighbor didn't mind as long as I clean up any mess he left.  Then 1 day, my dog  went thru the fence curtain and to the other side of the neighbors fence that he shares with another neighbor.  My dog for some strange reason, rammed his head through the new pieces of picket fence that his neighbor just installed.  

Of course now my dog has made himself look like he's aggressive and destructive.  I left messages to this owner that I will pay for any damages my dog has done or offered to repair it myself.  They never returned my call.  I tried again another month and a half later, and this time they told me that to replace 2 wooden fence pickets, she paid $100.  Of course there is no receipt or anything in detail from her repairman.  She sent me a copy of a check she made out to some man named Dave.  

When I look at her fence again, she now has a large border of 2x12 board running across the bottom about 4 or 5 feet.  

As a future home owner and pet owner, am I responsible to pay for additional items she added to her fence that were not there nor broken before by my dog?  Or do I just pay for the 2 fence pickets and labor to replace those 2 items?  

Am I allowed to ask for more detailed receipt, or am I allowed to request it directly from her repairman?  

Regarding my dog, I did everything I could do to try and prevent this from happening again, repaired my side of fence, repaired the neighbors side of his fence and haven't received money from him and his fence was never broken, but instead they are hanging by a thread due to water rot on all the boards.  And the cost of materials to replace on my and my neighbors fence so far has only run me up to about $65 and that's for more than 20 pieces of woods. 

I additionally have got my dog 2 behavioral lessons for abandonment distress, and still working with someone at SPCA to help for long term.  I've enrolled him in doggie daycare for times I cannot take him with me.  I've signed up to receive foster dogs to help find him a companion.  I quit my job and stay with him 24 hours a day.  I had to go to extremes, because this incident and a few other times he has gotten out because my roommate accidentally doesn't close the garage door when she leaves for work, or sometimes she doesnt close the front door hard enough to actually close securely.  He's is treated as if he is a wild dangerous predator roaming through the park.  

One night, I also witnessed a possom running along our fences, and saw for the first time my dog run to chase it away.  He normally is not a predator and knows to mind his own business.  But he did not like that possom.  I also noticed on some of the new fence pickets I just replaced, that some animal has been chewing through brand new wood.  I know for sure that it is not my dog because he has been by my side everyday and night, and....  he does not have teeth.  

We live in Sacramento California.  He is a true companion dog verified by licensed medical doctors.  I am feeling as though I'm constantly defending my dog, receiving lawyer letters regardng eviction because of my dog.
