Hi. What a cute little doxie. I am concerned with the dog eating stuff off the streets and sidewalk. Things on the street can be contaminated with antifreeze of gas, ever look at puddles after it rains and see rainbow colors? Also people put out pesticides on their lawns and various poisons for weeds and rodents which can be on things the dogs finds to eat while walking along a strange lawn. I may be a little overprotective but I watch my dog like a hawk when we go for walks so she doesn't eat anything. For walking her I'd suggest a head halter or other such device. Make sure you teach your mom how to use the halter properly.
