I’d agree with the others here, it’s all about setting a routine that suits both you and the dog(s)
I have a pair of springers who are regularly left alone from 0830 to 1530 and who seem to cope extremely well with this as they keep each other company. When they were younger we had a neighbour come in and let them out for 20 mins halfway through the day to let them out for a run in the garden but they manage fine nowadays curled up on a couch!
Spaniels as a breed make excellent family pets…..extremely tolerant of young kids as well as loving the outdoors, maybe a little too much whenever they spot something to chase as they seem to suffer from selective deafness!
But as long as you put in the hard work when they are young you can reap the benefits as they grow with the family.
Good luck with the search! 🙂
