Please can some one help me my dog eats but for some reason hailey is loosing weigh and has like a dry cough can u tell is that bad or what can i do to help her.

Bring her to the vet as soon as you can

Take your dog to the vet!

Sounded like kennel cough and also dogs won't eat in new home because changes in diet etc.. Vet next move

Vet.

Get to vet ASAP, nothing good causes weight loss except age and even then it needs to be looked at
