Hi guys am new here and I bought a 8weeks old female puppy last week... Shez really adorable and loves playing around... She was absolutely fine like till 2days ago when she developed a strange behavior.. whenever she's done with her games she just goes flat on the floor... it's cold here and the floors are very cold and damp... She really shivers when shez on the floor but even if we move her to a warm place she just won't stay there.. she just wants to literally stay on the floor and shiver.. I asked the vet if everything is ok and she says its ok... But am still in doubts as it doesn't looks normal to me.. Guys is it common with anyone of you???... Should I check with another vet??? Thanks for your replies everyone
