If you want a second dog get one. Do not get one for your dog.
A spinone will be a major life change from you have at present. Lots of mud, hair, love of puddles, will eat everything, a little bit thick |(sorry spinones! but you are!) , very happy, lovable, did I say love of mud and puddles, will demand exercise and not mind work but long muddy walks. Are you happy to be wiping drool off your kitchen cupboards, car windows, trousers, legs etc all the time.
If bored they will go self employed and chew and chew anything, Everything will cling to their coats from bracken, branchs twigs and did I mention mud.
You will find it quite hard to find a rescue Spinone if you are looking for one that is over 3 years old
Personally I would not trust anyone who considers themselves a dog whisper.
(speaking as an ex spinone owner - loved him to bits but you do need to , did I mention, love mud!)
