We have 2 Maltese X Shih Tzu pups that are almost 6 months old now. they are from the same litter, one male and one female.
A couple of days ago, Yoshi's (the male)behavour changed. He's not aggressive or anything, just seems to be particulaly needy now. he'll sit and sort of cry until he's picked up or comforted in some way, this wasn't the case before. over the last few nights he has also started running outside, (through the doggy-door) and barking for 10mins or so at a time, several times throughout the night. we've been bringing him back inside when this happens and then locking the doggy door closed. this seems to settle him down. Although the other night he was crying a number of times throughout the night as well. He also seems to be quite a bit lethargic. Still moving around, but jsut not as much as normal.
in addition to this, when he is sitting down, he kind of lifts one of his back legs up like maybe it is hurt or something.
We thought perhaps he had hurt his leg, i've throughly inspected it touching it etc and he doesn't seem to flinch or anything when it's pressed, perhaps it's a muscle strain?
i don't know if the lethargy and other behavour type things are related? i thought maybe it was his hormones starting to play a part, at almost 6 months he is probabbly going through puberty. it looks liek his testicles are dropping now as well, so perhaps that is causing him some discomfort when he sits like he used to?
We took him to the vet last night to get checked, she couldn 't find anything wrong with him at all, no injuries on his legs or ticks or anything.
anyone got any ideas out there?
