We are moving into our new house and we all want a dog. The problem is I have allergies. We were researching the low shedding dogs and saw a Cavachon. They are supposed to be low to no shedders. They are adorable and my kids are so excited- they named her Tinkerbell already. I do take Zyrtec when visiting family members that have 2 or 3 dogs. It works except at my Sil who has a Golden Retriever. Just wondering if I'm doing the right thing.
To answer your first question, yes there are dogs that are more allergy friendly than others.
I am assuming a Cavachon is a mutt, a cross between a Cavalier King Charles Spaniel and a Bichon Friese? It is definitely not a recognized breed.
If you really want an allergy friendly dog, getting a mutt that is a mix of one non-allergy friendly dog (Cavalier) and an allergy friendly one is not the best choice.
You could end up with a puppy that resembles his cavalier parent and sheds or you can end up with a puppy that resembles its bichon parent and be a bit more allergy friendly.
The thing with mutts is that there is no guarantee how the puppy will turn out, no matter what the designer mutt breeder tells you.
You would be much, much better off going with a pure bichon if you want guarantees of being allergy friendly.
There is a good thread somewhere on the first couple of pages that discusses some good options for finding your first dog.
Also, if you are bound and determined to get a mixed breed, please don't pay a petshop (puppy mill dogs) or some designer dog breeder big bucks for a mutt when you can find similar mixes in rescue and the local pound.
