Hi Julian....very sorry that your dogs may have caught fleas. Mine were treated about 6 weeks ago, so would be surprised if they are still in residence. They also had a bath in the last couple of weeks. The carpets were cleaned by me with a proper carpet cleaner a matter of two months ago. As mentioned virtually everything has to come through the front door so it does make life more difficult, than if that was not the case. I am aware that we all have different capability with our noses, to detect smells. So I could not disagree with your comments in that area. Because I have my two Jacks, it might not be so obvious. It is not normally mentioned, but has in the past, so you are not alone. I do feel that where the house does not get aired in the winter which I make a point of in the summer, it is likely that smells might be more prevalent. Not knowing where you might have taken them for a walk, I am very aware that the village does have many dogs, so it might well be others, or the local vegetation.
To finish, I am truly sad that your visit was less than perfect, but I have noted your honest comments and will do what I can. Thanks for not making any negative statements, much appreciated. Best regards for 2018.....Mike
