Dogtra iQ Mini Additional Receiver Rechargeable Waterproof Mini Remote Dog Training E-Collar

I got this for my 14lb small dog and it is just not a good design for my dog. I have one for my large dog which works well but can’t even use this collar for my small dog. The device on collar is much too large for small dogs. Very disappointed.

We had the larger version of this for our bigger dogs so I decided to add this mini IQ for our small dog so we can use the same remote. I love the ease of use but the mini IQ doesn’t hold a charge more than a day before needing to be put back on the charger. The older, bigger models hold a charge for at least 3 days. I returned my first mini IQ because I thought it was defective but so far the replacement doesn’t hold a charge more than a day either. It looks like I’m out of luck now because there isn’t an option to return this since it was an exchange.
