Yes, you can sue. I would do more than going to small claims court. I would consult a personal injury attorney in your area. I would also report the people to animal control. If you don't someone is going to get seriously hurt.
Contact Pierce County Animal Control. This behavior satisfies the definition of a "dangerous dog" in Washington. Keep reporting the incidents until animal control does something about it. You could also put up a fence. I'd be careful about shooting it with a pellet gun. You could end up with an animal cruelty complaint.
These are tough cases. There are several types of proceedings that can arise from these types of incidents and the outcomes can vary. If you are defending an administrative decision that has deemed your dog potentially dangerous, it could come down to the person that is overseeing your appeal. If that person abides by a strict interpretation of the code, you are out of luck. The provocation defense will not work. If that person is willing to negotiate, then it is possible that this defense can...
You should have a business license, insurance, and possibly create a business entity. The Washington State Bar Association Animal Law Section is having an all day seminar on equine law on January 29, 2013. It will cover topics of interest to you including insurance issues relevant to stable owners and trainers. We have a special rate for nonattorneys. For more information go the the Washington State Bar website and click on January 29, 2013 or give the bar a call.
Is the parking lot private property? If so, than the running at large provision probably doesn't apply. I would need to look at the police report and any statements to see what exactly was the basis for the charge. You should hire an attorney to assist you. If you can't afford an attorney, then a public defender will be appointed to you.
If you hardly have the funds for a legal battle, then at least have a lawyer review any agreement that he wants you to sign. You don't say whether your ex is an ex boyfriend or ex-husband which definitely makes a difference. Don't go to small claims! They can only award monetary damages.
Oral agreements, such as the one that you had with the seller of your dog, are enforceable. It just depends on how far the seller wants to take it if you breach the agreement. He would need to sue for breach of contract and replevin (return of personal property). I suggest contacting an animal attorney or contract attorney in your area. I would attempt to work something out before it gets to the point of defending against a lawsuit, but that is something to discuss with your attorney.
Yes, he can take you to court. Whether he will win is another matter. Take pictures of the texts to use in your defense. If the DNA test results show that his dog is not the sire, take those test results with you to court if he sues. It will be his burden to show that he was damaged and by how much. The ball is in his court. He must file a lawsuit if he wants to get half of the litter. If you have any emails documenting your discussions print them off and take them with you, too. If he hires an...
An owner of a dog is generally statutorily liable for the damage that that dog does to another animal. Provocation may be a defense. In Ocean Shores, "provocation" is defined as :taunting, teasing, willfully causing undue pain, and/or unlawful entry upon or into the property of the owner or keeper." I don't see a provocation defense here, but the other owner could attempt to assert it.
