@MalbecIsMyOne of course, my best friend is passionate about registered JRT and PRT and breeds both. Happy to help.
I got my first from her as a pup for DH on the farm, she went on to chose me. She came to work with me every day, and is the funniest, most loyal little friend ever. She's soft as muck, wouldn't harm a fly, but does bark the most. She rarely leaves my side. Pulled me from a dark depression following multiple losses and infertility, and adores Dd who somehow arrived.
I then took her mum, from breeder friend as whilst she was champion level at showing, she was becoming scared and came to the farm for the quiet. We refer to her as complex. She really does want quiet, gets quite anxious if we mess her routine. Timid, shy. Lead reactive though in town, rarely take her to be honest. Would lie down at trouble but barks to start it.
I then have the first ones daughter, so that gives me three generations, and another who I had sold, but the lady lost her husband and I took back under the contract. I think she will stay. She came back to rehome but I love her.
I walk off lead, number two can chase chickens but comes back. Number one hares but is food responsive.
In my opinion, PRT tend to chose a person. One and two are most certainly better for me, DH says they cry if I am out. They are less likely to recall immediately for him. Four is better for him. I think she realised she had to woo him to stay!
I could probably show them all at a decent level but I prefer the fun of agility.
They make me laugh every day. I fall over them every five minutes. My sofa is ridiculous, my bed used to be till Dd came along.
I find them different to JRT who can be more feisty, and possibly more tough. Mine are certainly soft, hate the rain, cold etc.
