Check with the state SPCA for some ideas. Ask your vet for suggestions of which associations may help. (Some vets will know, others won't; doesn't make them bad vets, just depends on their interests and focus.) Call the state bar association, they often will give referrals to 3 attorneys who work in the area you are interested in- animal welfare. Then check with those attorneys of which groups they think could help. (I am not suggesting you hire an attorney, you should be able to do all this free.)

I have never heard of this before and can't believe this declaw requirement can stay in force.
