We brought home our beautiful puppy at 8 weeks from a breeder we trusted because we had gotten our older Golden Retriever from him 10 years ago. She was on the small side, but cute and frisky as anything -- fabulous the first week and a half -- running and checking everything out and chasing her big sister's favorite ball etc. Just great at learning to go outside and not in crate....she loved running after her big sister, and took a spill or two in the yard from that bigger tail, but got up and kept going. We tried to keep her from being too rambunctious with her sister. Anyway at exactly the morning when she was 9.5 weeks old she woke up and would not walk out of the crate -- she would not walk at all. With a lot of work and support she would force herself up to poop or pee and with encouragement took a step or two every once in a while. We took her to the vet who said no idea what was wrong, but rest. She kept eating a little. We went to another vet friend who said no idea but exercise. Breeder said most important to eat lots of protein and drink and that she goes regularly. She did have a parasite called Coccidiosis, and is taking ALBON, but neither vet thinks this was any cause, as it is common for majority of puppies to have this type issue. She has no fever. Over holiday weekend no improvement and yesterday on day 6 she seemed a little worse and we returned to the vet who did xrays now and said nothing shows. Could be soft tissue damage or a strange parasite or something congenital. Breeder says it is a reaction to Lepto vaccine s he saw this years ago and had stopped having his puppies receive this, but a new vet gave it without his knowing. Says lots of protein and rest and she will likely work out of it. I do not know whom to believe. I think all mean well, but nobody knows.....one vet said go to a neurologist for MRI for $800, which I don't want to do if it is not needed since it is so costly, and I have an autistic child and 3 in college....the dog is a friend for the autistic child (young adult). Also said maybe specialist will do blood work to look for something rare before going for the MRI. Other vet who did xrays put on an anti inflamatory. She played last night on her back moving her legs rapidly as I dangled a stuffed toy for her. She ate when I ground up turkey meat with dry puppy food and warm water. I have also given her as much water as she will drink and some Pedialyte. After playing tonight she still could not stand, but she did poop for the first time in 24 hours. Sadly though she could not stand and squat as she had earlier in the week.....she kind of stayed on her side and went. Today she peed but cannot stand at all and moans once in a while when out of crate. Has eaten a little turkey and had a bit of water. Anyway, this is tons of info, but I would welcome any help anyone can offer as she is so very dear and loved already in two weeks (in two minutes!) and we do not want to see her unable to walk or enjoy a fun "puppyhood." We saw her being the ultimate happy little playful girl, and do not want to see that taken from her or her "boy." Thank you for any thoughts.
