Mark is approximately 6-7 years old and is likely a lab/rot mix. We've had him since he was a puppy and while he is fine with most dogs and cats, he will chase cats that run from him (outdoors). He is fine around chickens and horses, but not goats. He can be very energetic at times but is calm at times too. He is crate trained and has been indoors and outdoors. He is completely house trained and is great around kids and adults. He gets a little aggressive toward other dogs at feeding time and is the dominant dog here but I have seen him act submissive around my parents male dog. To an approved home only. We are adopting him out due to the fact that he has killed several feral cats and is aggressive toward our goats.
