hello, this is my first post and it's in regards to my 17 year old green iguana, Cozmo. I have had Cozmo his whole life and he grew up with dogs and is unbelievably tame. He could eat out of the same bowl as one of my dogs, and he has, that's how laid back he is. When I had first got him I was living in Michigan and he had a cage with a heat lamp and heating stone, everything that he needed to be healthy. I moved to South Florida when he was about a year and a half and when that happened, we decided he no longer needed a cage because he got natural sun from laying around the pool all day. About two years ago Cozmo started to charge after my white schnauzer, Kapser. When he finally gets to Kasper, sometimes Cozmo just stands there, other times when he has charged towards him he has tried to climb up on his back, almost like he is trying to mate with Kasper. I have a black scottie and my sister has my scottie's sister and she also has a yellow mutt. The dog who he was raised with was also a black scottie and he has never tried to go after any of the other dogs, he just recently became obsessed with Kasper. Kasper is terrified of Cozmo now, because every time Cozmo sees Kasper, Cozmo gets up very high and charges at him. We have to keep them separate at all times because of this. One time Cozmo jumped up onto a couch that Kasper had jumped up on to try to get away from Cozmo and Cozmo jumped up with him, Kasper showed his teeth to Cozmo and Cozmo bit Kasper. Cozmo is obsessed with my dog! We have to keep our slider doors closed so that Cozmo doesn't get in the house to get Kasper. Cozmo will spend hours scratching at the glass doors, trying to get inside to get to Kasper. Has anyone heard of this kind of behavior? My sister and I brought him to an exotic vet for the first time in his adult life because of this, because of this we didn't know there were different exotic vets, this vet was an avian vet and the whole office had never even seen an iguana as big as Cozmo. The vet couldn't even tell us what sex he was, we had to send his DNA to place in CA to find out. She said that the reason he was doing this was because he needed to be fixed or injected with hormone shots, both of these options are insanely expensive and the fact that she couldn't even tell the difference between a male and female adult iguana leads me to believe that she wasn't really an expert on iguanas. so I'm clueless and have no idea where to go from here. I have a YouTube video of Cozmo charging after Cozmo but it won't let me post it., if you'd like to see it please don't hesitate to contact me. Could it be that he thinks that he's a dog, seeing as he has only ever been around dogs. Help!!!
