I want to get a dog but I have to work, how does everyone on broadway market do it ?

I’ll tell the story of Dolly’s puppy classes
Dolly was 2 year oldish at the time.
She is a Jack Russell Beagle cross and is a rescue dog, that had lived in a field for around 6 months immediately before we picked her up. Before that she had had a litter of Jackabees for the horror show that had her before us.
Anyway she got the hang of being in a house instantly, so I guess at sometime she had been in one. But she wouldn’t walk on a lead and did whatever she wanted no matter what utube things we tried.
So puppy classes were suggested by the local trainer. She was obviously the only grown dog there, but did ok with Sit, Wait, Stay but that was it. The trainer said we needed better fridge treats and that would get her to do the harder stuff.
Fast forward to the last week and recall. The trainer had her own never fail treats. The first 5 puppies did it perfectly. Then came Dolly, she had been watching intently so knew what to do.
The trainer walked her across the field and sat her down, Liz and I had the special never fail treat and call her over. Like a super star she runs straight towards us, the pride I felt was real (she’d never come when called before), it was short lived, she ran straight past us, into the lean to that the trains used to store stuff. She came back out with a ziplock bag of the special never fail treats and went and sat behind us to devour them.
The trainer said that older Jacks are hard to train as are older Beagles as they are too smart to be bought and good luck, you’re on your own though.
Fast forward a year and she still has no recall, still won’t drop stuff when asked, but she will freeze so at least we can get to her if she runs off or is eating a rat she’s pulled out of the hedge, (if ratting was her job she would be employee of the year) if we are quick we can grab her.
In every other respect she’s brilliant, but I wish she’d come when called.
