I've noticed a lump at the top of my bearded dragons stomach on his right side it is mostly circular and smooth but one side is a little lumpy it feels about the size of a peanut maybe a bit smaller it's not visible from the outside and can only be felt when massaging it I can also move it around his belly but it seems to always settle back on his right side he is quite an old boy at about 10.5 years old it doesn't seem to bother him and I have managed to get him to poo I've noticed that he's also a little clumsy when walking he is eating but not as much as usual because it's winter and he's brumating I took him to my vet who's not a specialist but knows a good amount about reptiles and he said he's lost a bit of weight and to try fatten him up a bit just wondering what everyones advise is ?
