Hi and welcome David to this forum. Sorry I can't help with your question, but if you are concerned contact one of the TM associations or your dog's breeder. There won't be a set weight as all dogs even of the same breed will differ, there will just be a 'range'. I have littermate TT's who are nearly 2yrs and one weighs two and half kilos more than the other and both are males. Good luck and I'm sure we'd all love to see a photo of your pup.
As above then best place to ask is your breeder first, or the breed club. Weight guidelines are just that guidelines, if your girl is looking healthy and not to thin or heavy , growing at a steady rate and is eating, then don't get to hung up on what the guidelines say. What has the breeder got to say, they should give you all the support you need.
