Skinny, short-haired dogs really ought not to be left out in 40 degree weather for more than an hour.
I wasn’t going to say anything but since someone else brought it up…
Although I grew up with dogs I don’t really have solid knowledge about caring for them. So I did some research into dog care, focusing on 6 month-old puppy care and weather tolerance specific to English Pointers. From what you described, it’s possible that you were not caring for your dog properly.
While German Pointers may tolerate the cold well, English Pointers do not. Puppies are even less tolerant. Upon review of some animal care legislation, I found that some areas prohibit keeping dogs outside when the temperature drops below 40. You said that the water in his bowl was freezing. That means you were keeping him outside when it was below 32 degrees. While such legislation may not exist in your area, I present it only as an indication that “experts†may consider your care negligent for keeping the dog outside, especially since the dog is a puppy. Unless the garage was heated, I don’t think that offers much defense.
As for feeding him, from my research it appears that you were on the low end of “appropriate.†However, because you were keeping the dog outside in very cold weather, the dog would have consumed a large amount of energy just to keep warm. This is very bad for 6-month-old puppies. A 6-month-old puppy is nearly full size and eats about twice the amount of food an adult will because the dog is still growing. Since the dog was expending so much energy in heating itself, it is possible that the dog could presently be malnourished.
My layman’s assessment is that you’re in serious trouble. You MUST get a lawyer that is familiar with these types of cases and you MUST get a vet to examine the dog AND examine test results from tests taken when the dog was brought in. This is important because the animal will recover (IF there was anything to recover from) fairly quickly once the vet starts pumping him full of antibiotics and other quick-healing drugs and nutrients. In two days a dog in bad shape can be in okay shape.
If no tests were performed on the dog, then it’s the vet’s word against yours. You can use this fact in your defense, as the vet couldn’t really know for sure if the dog was malnourished without testing. Expert opinion is powerful testimony, but it is still only testimony, not evidence.
English Pointers need lots of space…they need to roam. Keeping such a dog in a 10x12 cage is not good for the dog’s mental health.
Good Luck. I’m afraid that you’re going to need it.
