Hi, my 2 yrs old rottweiler She-Ra, has problems in gaining
weight and does not produce any litters (puppies). She also constantly has parasites problems(worms). As far as I have been able to understand from checking on the internet, it can very possibly be due to thyroidal problems. Can you tell me if this could be the case, what test should be conclusive for this, and if treatment would cure her completely, how long the treatment should be, and if she can have puppies after treatment ?
