If it was a purebred Newf, I would worry about it’s care and feeding during it’s puppyhood, as they must be fed properly for proper bone growth. However, that may not be as much of an issue with a mix.
I have no experience with Newf mixes, but I do have experience with purebred Newfs.
Large, lovable, messy, loyal, great with kids. Will fit their activity to YOUR lifestyle- if you are active, the dog will be too, but he is just as happy to hang out on the couch.
A mix may solve the drooling problem- look closely at this dog while at the shelter, especially after drinking water. Think Turner & Hootch. I have drool 6 feet up my walls from strong head-shaking. Also, daily brushing is a must, as is a good vet who knows your breed very well.
Although they are huge, they don’t necessarily need to eat a ton of food. Check with your vet. A strict diet can help relieve pressure on joints in big dogs.
Our Newfs range from 135 lbs (bitch) to 170 lbs (dogs), with an average of about 150 lbs. They take up a lot of room in the house, on the bed and on the couch.
They are the most amazing, loving, gentle giants I have ever known, and I highly recommend the breed to experienced large-breed owners.
A mix could be lovely. Spend as much time as you can with the dog, and get as much history as you can on how it was raised, the sire and bitch, etc. Good luck and have fun!
