I had a german shorthair and he had a lot of health issues . This is a breed that is not too popular because of their independence and high energy .I think a lot of his issues were due to certain immunizations given far too early and also the breeder .
We could never find out much about him . He was a gift to my son . it was a very nice dog and we got through it all and he lived aa good life .
My friend has a female Havanese and she had to have surgery on both of her legs . She supposedly came from a reputable breeder who did all the right things and tests . Tulip is fine today - a sweet dog 6 years old a great companion dog .
One thing about getting an older dog is you do not have the puppy training and some other behaviour issues but you also have to retrain them to your home and lifestyle . There is a period of adjustment and they need extra TLC .
I think you should read the Havanese book by Dorothy Goodale - thank goodness it was the only book avaialble when I got Asta .It did not deter me .
Some of the books tell you more about elephants than you really want to know . Maybe better to skip certain chapters . I never read about breeding as I did not want to breed . Others have different motivation and need for certain information as they want to show and breed ..
Not one day was I sorry that I got this breed - Asta was an incredible dog .
I have my two new ones and they are wonderful as well . Different personalities for sure but they sure are cute and smart too ..
I agree it all depends on the breeder .
I went on line and I could not believe some of the stuff I saw . It just broke my heart . Breeders sacrificing their Havanese at discount prices because they decided to stick to breeding large dogs ..
Some are not breeding for the integrity of the breed but purely for monetary reasons
