New to this. Best weather in winter??? Help?

Millions of people live in Arizona and it seems the majority have dogs. Neither is a problem.
Yes, it CAN happen but it's no problem.......
Dogs can have issues in other states from ticks, fleas, alligators and copperheads, too.

To say it is 'not a problem' is a very "inaccurate" statement. It IS a problem and can be fatal to a large percent of those that get it. If diagnosed early it can be treated but is a long enduring process and not always a good outcome.

It is found in the ground which is EVERYWHERE in this region. Hard to pick a spot to camp where there is no ground!

Ticks, fleas are preventable, NOT a severe and/or fatal disease.
Alligators? I don't let my dogs swim in the lakes of Florida.

Copperheads?
"The Southern Copperhead is limited in the state of Florida to the panhandle region, and is not particularly common there, which means most residents of Florida will not encounter one unless they leave the state.//...timber rattlesnakes have a limited range in Florida. .... and timber rattlesnakes are only found in northern Florida..... Florida's other venomous snakes occur in a variety of natural habitats, ranging from swamps..."

I don't camp in the swamps of Florida! :W

I was not aware of Valley Fever until a friend of mine's dog died from it in California. Finding out ONLY after an autopsy was performed.

'Many' more dogs that are not documented die from it because it goes diagnosed until it's too late and the dogs have to be euthanized the owners not knowing why unless an autopsy if performed which almost no owner wants to pay for.

I was made aware of it and "I" personally chose not to RV in that area with my dogs. I am glad I learned about it.
