Thas a good question. I know my baby had a problem with the beginning sounds in words like the sit and stand because of the S sound so i had to do a different word for stand so i used the japanese word for stand which starts with a k.
I know that I have a problem with my neighbors bulldogs Dolly and Dally...
I think the dogs can get confused off of that..
I think because u started with two different constants that start their names it will be ok.
