Why is my dogs anus swollen?

The pet HAS a vet. Or do you think humane societies do stuff like that (particularly the rabies vaccine, which is regulated, and the spaying/surgery) without veterinary help?

What you can say instead of saying “no veterinarians are needed”, is “there are organizations, such as humane societies, which have partnered with veterinarians and veterinary clinics to offer some basic services for a reduced or free price”.

Thanks, I missed that in the info dump there, reading off my phone. At least that’s something.

You know, you can buy vaccinations for a dog or cat at a farm store. In Indiana, we can buy 6 and 7 way vacs for our dogs. Only a Rabies vaccination administered by a vet is legally recognized in Indiana, but we have what they call “Rabies Roundups” where you can get one year shots for about $8 or three year shots for about $24.
In Kentucky, it’s even better, you can buy the rabies and every other vac you need and administer them yourself. So that is how on earth it can be done.

Best part: Dog smoking a cigarette after the procedure.

Well, it was posted by BELLAtheYORKIE, which is obviously a Yorkshire Terrier named Bella. And Yorkshire terriers are known to be terrible about checking the dates on posts.

Vets are expensive, but search around for a low cost one. We have one that we take out animals to. It’s about a thirty mile drive, but the Vet is caring, the staff is great and the prices are about half of a traditional Vet. The building is older and the waiting room lacks any niceties, but I’d rather wait in an uncomfortable chair and pay a little then sit in a leather one and paying through the nose for it.

Zombie dogs don’t care about anal glands.

When my (late—RIP, Buster) Boston terrier was a puppy she had a rectal prolapse, and as much as an inch or more of her anus would protrude when she was squatting to poop. The poor little thing would stagger around the yard trying to maintain her squatting position, and only passed her stool with great difficulty. We immediately took her to the vet, who anesthetized her and digitally stretched her anus. He told us it was just a not-uncommon congenital defect that he was able to remedy without surgery. She was quickly back to normal and was an important part of the family for the next 14 years.
