So,

 
 
It's time to get to your nearest pet shop and get one of these:
Because, you can tie a plastic bag to you lead ... but if you:              

sometimes forget your litter bags

 

occasionally dirty your hands while picking up after your dog

  

find it unpleasant carrying full poop bags

 

get a sore hand from holding the lead

 

have a strong puller

  

have trouble controlling two or more dogs

  

would like an extra pocket

 

then ezeleash is there to help
