Well you can never be too sure about this breed... 3 breeds are alot similar... i.e. Italian Volpino, Samoyed and Spitz... Lets see to make it clear this is commonly known as the Russian dog here or the pisti nasal by locals...
This one here is either an Italian Volpino or a Spitz... Not too sure coz even my friend who gave me this pup said eh Russian nasal ha...
Yes they have standing ears but full standing and very good guard dogs... ofcourse they are small in size and can be considered as toy dogs... 
Cant deleiver it anywhere ask someone to pick it up on your behalf and pay me 
Consider the price final...
They have no issues whatsoever with temperature of Pakistan...
