Without further information it is very difficult for me to provide the best advice but I shall certainly try.
Please reply when you can and we can continue the conversation.
From your dog's name, I suspect you may have a Pug? These dogs are very prone to Intervertebral Disc Disease which can present as a sudden lameness, weakness, lack of sensation to the paws or even paralysis.
If your dog has become suddenly affected (rather than getting slow and stiff over time), an urgent vet appointment is advised.
They will examine Puggles and may run some tests such as a neurological assessment, orthopaedic exam and some imaging.
Treatment will depend on what is going on and may include e.g anti inflammatories and pain relief.
