>>I am interested in having an iguana in my life, but I wasn't sure if that it would be the best pet for me. I have reptile experience and I currently have 2 Leopard Tortoises. I do have to take into consideration that I have a very large and hyper dog and my husband and I go camping a lot. I didn't know if they liked to go on vacation or who could watch such a large reptile.
Whenever someone asks "Does [species name] make a good pet?" I always want to ask "Define good."
Tortoises are very different than iguanas. I have three tortoises, 2 box turtles, a teeny leaf turtle, a blue-tongue skink, and together they are less work than my one iguana. The 'one' is notable because for years I had as many as 22 green iguanas (most sexually mature males) here at one time, back when I was doing ig rescue and rehab.
Some igs get along with some dogs; some don't get along with any dogs. Fear often tranlates into agression towards the feared object, so the size disparity doesn't necessarily matter, especially if the dog is one who is actually not particularly bothered by the iguana. Some dogs are, and will cheerfully try to make the iguana into a chew toy when not supervised. And did I mention, accidents always eventually happen?
Some people take their igs on vacation, schlepping a portable enclosure, bowls, heat lamps and pads, power strips, towels, paper towels and disinfectant, a cooler of iguana food, and food prep utencils. Oh, wait. You're going camping? I take it that you don't mean camping in, say, a motel?
Aside from the difficulty in providing at a campsite the tropical temps iguanas need, there is also the matter of why people go on vacation, especially camping. They want to get away, relax, maybe do some hiking, rock climbing, fishing. All of which is difficult if not impossible for at least one of them to do when there is an iguana to be kept safe and secure.
It can be difficult to find pet sitters who really know how to care for iguanas. Oh, yes, there are people who say they do, but what they really mean is "Yes, I can come in and put the food you pre-prepared into a bowl and put the bowl into the cage and maybe get yesterday's bowl out of there and cleaned for the next day's use."
What they don't mean is "Yes, I'm comfortable catching and picking up and carrying iguanas who really don't want me to, so I can take him into the bathroom and run his bath to potty him, and then let him soak for a half hour or so, while I clean and straighten out the enclosure and make more food (including going shopping for it and preparing it properly) because it's summer and he is consuming more than you thought he would so we ran out while you're still gone."
One way to find iguana-experienced pet sitters is through your local herp society, reptile rescue, and reptile vet office. If you don't already know who is in your area, check out the lists and resources at my Herp Veterinarians and Herp Societies & Rescues web pages.
And, speaking of my website, if you haven’t already done so, please read my Iguana Care, Feeding & Socialization article. It is linked to my Green Iguana Care page, where you will find lots of other information you should read before deciding on an iguana - especially the one on Breeding Season Basics.
Other than that, and apart from the multitudes of bite and claw scars on my arms and the sky-high utility bills, sure, igs make great pets - if you're willing to turn your home and life upside down for them.
