Not at all. The U.S. does not pay for any type of service or guide dog. However, the veterans administration—if you are a veteran who was honourably discharged—does provide veterinary health benefits for the dog, if it's an ADI or IGDF accredited dog. But, no, the government does not pay for the dog.
I'm talking right now, when I brought up the PAWS Act, about some funding that is still on the House floor. If it comes to fruition we'll be very lucky. Some programs will get funding.
