I just got a male boxer that is 1 year old, When we got him home we weighed him and he weighed 47 lbs. We did have to worm him for a tapeworm and he was gaining some weight but now he is throwing up and his hair is still thinning I thought he could have a thyroid but not sure. We also changes his food to a better dog food and we haven't been giving him any table food. I just don't know what to do. Help?
i work at a animal shelter and we deal with this stuff everyday what you need to do is get a wormer by the name of panacur and give him 1cc per ten pound for three days straight he probably has whip worms and hookworms which will cause loss of appt. throwing up, runny stool and can cause hair loss due to the strees of the worms and they can also cause death . you should be able to find this wormer at any feed store. it is for cattle but very safe for dogs. good luck.
with a thyroid condition in a dog you will usually see them gaining a lot of weight and they will have bi lateral patches of hairloss usually near their hind end , on their sides. that is a classic sign of thyroid disease. sometimes they will have thyroid disease and not be showing signs and/or have a normal t3 and t4 result. in which case you need to have more extensive thyroid testing done. throwing up is usually a sign of thyroid disease in cats and not dogs. if the hair loss isnt symetrical on the dogs body, and is sporadic you may want to have him checked for sarcoptic and/or demodectic mange. a simple skin scraping done by your vet will rule that out. though sometimes demodex can be difficult to catch on an initial skin scraping.
in any event, a trip to your vet before he gets any worse is in order. good luck
