My dog has swelling around his eyes, and a swollen anus (including the area between his testicals and anus). He is panting with a slightly accelerated heart rate. He has moderate dripping of saliva from his mouth, and his gums and tongue are 'redder' than usual. He will not lift his tail, and yelps when I attempted to gently lift his tail. He allowed me to put my fingers underneath, but was very tense and softly whimpering. He is shaking, but does not have trouble walking. He will not sit directly on his butt. He attempted to urinate, but stopped- almost like it was to painful. I don't know if that is because of the swelling and it was to painful to do the 'puppy squat', or if he is having trouble urinating. He just turned 1 yo in April, and is not nutured. I dropped about 10 (washed) blueberries and he ate them- that was at about 3 today. This started late this afternoon.

This dog is not peeing or pooping? He needs to see a vet! I hope he survives the night. Is there an emergency clinic in your area?

This needs to be addressed with a vet in person. No one here will be able to tell you what is wrong with your dog, what I can tell you is that a lot of what you are describing are indicative of your dog being in a good deal of pain for whatever reason.
Please get him to the vet ASAP.

Get the dog to the vet yesterday, sounds like a very bad case of worms but I don't an can't say for sure. Do not waste any time today, take him straight to any vet that you can now!!

Most likely something more serious would you please stop chalking everything up to worms.
Worms are only one of the problems dogs can encounter in their lifetime.

Read the end, the first 5 can be contributed to dog food or worms. Would like me to prove this also. This was my opinion, everyone has one!

The Five Most Common Dog Physical Problems

What are the most common dog diseases and health problems? In 2008, a popular pet health insurance provider (VPI) evaluated this issue and released the following results, listed in order of frequency:

The most common health problems in dogs are:

1. Ear Infections 2. Skin Allergies 3. Pyoderma/Hot Spots 4. Gastritis/Vomiting 5. Enteritis/Diarrhea

Rounding out the top ten in their survey were: urinary tract infections, benign skin tumors, Osteoarthritis, eye inflammation and Hypothyroidism.

These ten dog health problems accounted for nearly 25% of all dog health insurance claims.

Not included in VPI's list but other highly prevalent canine health concerns are: parasites (worms, fleas, ticks), Gastric Dilatation-Volvulus ("GDV") - commonly known as bloat, and obesity.

It is recommended that you make a list of these health concerns (the ten in VPI's survey plus parasites, bloat, and obesity) and bring them with you to veterinary appointments.

A more comprehensive list of things that ail dogs and cats.
There are many more than five.
For starters no one here can diagnose, this is the internet it is not possible.
I could point out lots of possibilities from this list of symptoms, not just worms.
Do you see what I am getting at?
OP reads "case of worms" and doesn't see much urgency for treatment, it's just worms.
Swollen eyes-allergic reaction, bee sting, demodex, I don't know.
Swollen anus- over full anal glands, perianal hernia, mass or tumor, I don't know
Panting and accelerated heart rate-cardiac problem, anemia, got too hot, I don't know.
Hyper salivation-ingested something toxic, nauseated, I don't know.
Reddened gums and tongue-heat stroke, the bruising that comes with ingesting rat poison, I don't know.
Yelps, tense and whimpering-likely a reaction to pain, but to what, I don't know.
Attempted to urinate and would or could not finish-urinary tract infection, kidney problems, stones or just too painful to assume the position, I don't know.
It all came on rather suddenly, worms don't do this, sorry.

As far as your VPI statistics.
1-This is what they covered, I've seen them disqualify pets for more serious issues that obviously are more costly.
2-That is only a study of the pets who had the insurance, I would be interested to know what percentage of the pet population actually have insurance, I'm betting it is pretty small.
3-What problems take up the other 75%?

I am not trying to argue with you but you cannot minimize what people are saying by stating something like it sounds like a bad case of worms because it may very well be much more serious. And what happened? They didn't get their pet looked at in a timely manner.
Granted some will not and may not need to seek medical attention, but that is why they come and ask the question. Many get the medical check up and come back to thank us for helping them see the urgency in it.
In this post I see a very sick pet far beyond dewormers.
