thankyou all for your kind replies! she is a little sweetheart & we love her dearly. i have made an appointment with a different vet for tomorrow morning. we'll see what he thinks & get the blood test. i've been meaning to see him re: her dental issues anyway as he is the local pet dentist. hopefully he is knowledable in regards to my concerns.
i didn't realise there was such a thing as dwarfism in gsds. i've been reading about runts up until now. i'm surprised one of the vets hasn't mentioned dwarfism until today, nor do they seem concerned about finding out at all. i've now had a look at a lot of info. it seems it would be better to find out sooner rather than later so we can start her on any medication if needed. i don't mind her being small at all, as long as i can give her what she needs to be happy & healthy...
