No...it doesn't sound good at all. I'm very, very sorry to hear it. Yes - a vet trip is in order, I would never argue against finding and using a qualified veterinaran, however it is absolutely NO guarantee that the vet you found will help...and if he's in such a weakened condition he may not pull through even with vet help...I was in a similar situation and the vet promptly put him in a warm (not hot) bath, kept him for 3 or 4 days, tube-fed him, treated him with antibiotics (for respiratory problems)liquid calcium supplement (for calcium deficiency), ran a fecal test and treated him for parasites...all treatments I had to continue at home every day for over a month - including outside "sunshine" time (?) (20 min. a day) Overkill? Probably ...but it worked. I think my monitor is slightly "damaged" from the ordeal, but it's been close to 2 years now and we're alright.
Any chance you purchased your lizard at a chain-store "15 day guarantee" place? Any chance it's still within the 15 days? If so - try to take advantage of it. I made the mistake of buying my savannah at one of those big chain store operations, and I went back there and THREW A FIT until THEY paid my $450 vet bill. It all worked out in the end, a miracle, but I wouldn't wish it upon anyone.
In the meantime, keep him warm, let him hide. If there are any crickets in his enclosure now - take them out...crickets might nibble on him and stress him out even more.
Where are you located? I really wish I could help somehow - though I know there isn't much I can do. You're welcome to my leftover medicine
As a last ditch effort - try a warm bath. Maybe it'll perk him up enough to eat a cricket...and if crickets are too difficult for him to catch, cripple one for him so he doesn't have to run for it. supplement with calcium. If he's still not eating - don't force it.
Last note - sometimes they die. The only way you have a fighting chance is (a) getting your enclosure to where it can sustain a healthy monitor, and (b) knowing what you are buying - looking for signs of a healthy baby savannah monitor, and only purchasing what looks "good" - fighting, fat, angry...
Maybe he'll pull through?...let us know either way.
