Yes. I had my six year old dog put to sleep just a year ago, inoperable, brutal tumour. I’d expected us to grow old together. I have an 11 year old labradoodle and several months ago a ten month old spaniel joined us. I’ve rescued and fostered dogs for forty five years but given four grandchildren under four felt it wouldn’t be right to bring an unknown adult dog into our family. The spaniel came via a friend, for good reasons. She’d been loved and cared for, that plus the spaniel temperament means she’s perfect for us.
I’m 70. My sisters and adult children would take our dogs if disaster strikes.
I volunteer for a specific breed charity. We’ve placed dogs with older people. Go for it, you’ll not regret it
